Applies To Product(s): SewerGEMS, CivilStorm Version(s): V8i SELECTseries 4 (08.11.04.54) Original Author: Sushma Choure, Bentley Technical Support Group Overview The SELECTSeries 4 release of SewerGEMS and CivilStorm includes many new features and improvements. This technote explores these new changes. New Database Format Independent of Microsoft Office Support for Newer Platforms and Operating Systems SCADA Connect (SewerGEMS only) SCADA Element (SewerGEMS only) Hydrogen Sulfide Modeling Digital Terrain Models Headwall Elements PondMaker Bentley Map Mobile Direct import of MX Drainage files ProjectWise Cross Discipline Downstream trace Redesigned conduit catalog Improvements to automated design Drop Structure New Hydrograph & Loss Methods New time of concentration methods Storage Chambers Improvements to Calculation Options Enhancements in Network Navigator (SewerGEMS only) Global Storm Events Inlet-only hydraulic calculations Sparkline in Flex Tables EPS Results Table EQT curve Surcharge-Overflow For a free Webinar covering these features, click this link . New Database Format From this SS4 version, SQLite is used as the database format. (Previously it was Microsoft Access Database (MDB). There are some noticeable advantages with the SQLite database, such as: • Smaller database files (50% smaller than MDBs in average). • Smaller deployment – SQLite’s library is less than 1 MB, compared to MDB’s which is 25MB+. • Transparent cross-platform support (x86, x64 – and others) with no conflicts with other programs like Microsoft Office. • Cross-device support (Desktop PCs, smartphones, tablets, etc.). • Faster than MDBs in general (percentage varies per type of query/operation). The database will now be *.stsw.sqlite Independent of Microsoft Office There is no longer a dependence on Microsoft Office, whether it’s 32 bit or 64 bit. Therefore, there are no longer any problems integrating with 64-bit AutoCAD when using 32-bit Microsoft Office. Support for Newer Platforms and Operating Systems The following platforms are now supported: Windows 8.1 (32/64 bit) AutoCAD 2014, 2015 (32 bit/64 bit) MicroStation V8i SELECTseries 3 ArcGIS 10.2, 10.2 SP1 (SewerGEMS only) ProjectWise V8i *Please note that SS4 no longer supports Windows XP or Windows server 2003 . SCADAConnect Note: this feature is only available in SewerGEMS. SCADA connection will now be available, live data connections can be set up to SCADA systems, so that SCADA data can be used for calibration purposes and real-time simulations. SCADA data can be added from different sources like ODBC, OLEDB, SQL, oracle connection, Access, Excel etc. Data can be real time or historical. More information can be found in the help documentation. To use this function go to Tools>SCADAConnect. Here you can define the SCADA signal, SCADA element's properties and SCADA log, initial settings can be imported as well. A SewerGEMS license includes an unlimited SCADA signals for use in SCADAConnect. SCADA Element Note: this feature is only available in SewerGEMS. SCADA element has been added to support SCADA connection. This element represents a real-world SCADA signal that is associated with a hydraulic element in the model. It displays both real-time and historical SCADA data as well as the difference between SCADA and model results. Detailed information on the SCADA Element can be found in the New SCADA Element solution. (Please visit the site to view this video) Hydrogen Sulfide Modeling Hydrogen sulfide formation in pipes can now be modeled with nodes and wet wells, when using the Explicit (SWMM) solver. Sulfur exists in many organic and inorganic forms. For wastewater, the prevalent forms are sulfate (SO-4), hydrogen sulfide (H2S) and hydrosulfide (HS-). Sulfate is found in all wastewater in high concentration, so there was a need of introducing the option of hydrogen sulfide modeling in SewerGEMS, so this feature has been added. To run a hydrogen sulfide model, the explicit solver must be selected in the Calculation Options or Compute Center and run Hydrogen Sulfide Analysis needs to be set to True in the Calculation Options. For more information on modeling hydrogen sulfide, see the below article and imbedded video: Modeling septicity / hydrogen sulfide (H2S) Digital Terrain Models This new tool has been introduced, which automatically assigns elevation data to node elements, including manholes. The node elevation can be updated automatically when the element is moved. Terrain models in the form of *.tin, *.dtm, *fil, *.xml, *.dgn can be imported. The .dgn file can be imported in Microstation platform only. The terrain model file also can be accessed from ProjectWise, if integrated. Multiple terrain models can be imported, but only one terrain model can be active at a time. (Please visit the site to view this video) Headwall Elements New feature has been added which supports culvert headwalls and endwalls, which can connect to open channels or closed conduits. Headwall elements are node elements which enable the modeler to better model conduit and culvert headwalls and endwalls. Headwall elements can be used to model any transition from/to an open channel or pond for/to a closed conduit. Only a conduit link can be used to model a culvert. New culvert inlet coefficient library has been added to design the culverts. In previous versions to design culvert you needed to choose the option is culvert to ‘True’ in the properties of the conduit. But now headwall has been added as separate element for designing culverts which allows for defining Culvert Physical properties in the headwall element itself rather than the Conduit. Below are some possible combinations of headwall elements. To understand the Headwall elements briefly please see the support solution below. http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/16005.headwall.aspx PondMaker PondMaker tool has been introduced in SS4. It’s an easy step-by-step detention pond and outlet structure design tool. PondMaker was originally implemented for PondPack, now it has been included in SewerGEMS & CivilStorm. So with this release ponds also can be designed. It’s available for Implicit (SewerGEMS), Explicit (SWMM), and GVF Convex solver, but not for GVF Rational solver. Bentley Map Mobile It’s possible now to view SewerGEMS/CivilStorm models on Android, iPad & iPad mini tablets; you just need to have the Bentley Map mobile application. The new tool has been introduced-Bentley Map Mobile, which publishes map mobile i-model, available in file export options. Even background files can be viewed but individually in the view filter list in map mobile. This tool is beneficial for the users who don’t have Bentley software; the models can still be sent to them so that they can view the models on their Android, iPad & iPad mini tablets. Direct import of MX Drainage files The import of MX Drainage files has been improved, reducing the steps necessary to leverage MX Drainage data. To import drainage data from MX, you would go to File > Import > MX Drainage. Before you can use this option the following requirements must be met. You must have MX build 08.11.09.700 or later installed on the computer for the import process to work, but it does not need to be running. You can only import data if you are using the 32 bit version of the Storm-Sewer products. If you are using the 64 bit version (by default you will be on a 64 bit operating system) then you will get a message telling you that the functionality is not available. To run the 32 bit version, locate the relevant exe in Windows Explorer, and double-click it to start the product. For example, for SewerGEMS browse to "C:\Program Files (x86)\Bentley\SewerGEMS8", and double-click on SewerGEMS.exe. You can import MX Drainage data to both new and existing project, however, you can only import to existing projects that contain no elements in the model. There is a section in the help titled "Importing from MX". In this section it explains how the MX Drainage data (nodes and pipes) is mapped. ProjectWise Cross-Discipline Coordination Services ProjectWise Cross-discipline Coordination Services refers to a shared library of code and tools used to facilitate the communication of model engineering data between two or more separate applications. Repository management allows communication between two different applications, one being SewerGEMS. Repository needs to be created for this, through File>Repository Management>Create/update Repository. For example, suppose the building construction software wants to communicate relevant information about the model with the software being used to design the parking lot for the building. PWXDCS allows this communication through a separate store of information called a consensus repository. This consensus repository has a schema called the consensus schema. The consensus schema only contains those fields/attributes that are common/relevant to the software using it to sync data (in this example, the common fields/attributes between the building software and the parking lot software). Below is the workflow: Downstream Trace The new tool has been added called Downstream Trace which works with Terrain models. Once you have the terrain model active, then you can find the path from a start point to a lower point with greatest gradient. The trace may stop at a local low point if we do not ignore local depressions; the trace can stop at a lower downstream point if we ignore local depressions. The downstream results can be deleted once viewed. Downstream trace is ability to trace water drop so that users can place inlets at proper locations according to the catchment delineation. It helps in deciding the inlet locations according to the catchment boundaries & gradient. Redesigned conduit catalog In SS4, the conduit catalog has been redesigned in more user-friendly manner. Wherein you can edit the properties like Manning’s n, wall thickness etc. in the conduit catalog for all the selected sizes at a time. Improvements to automated design The automated design is more improved now, with enhancements like pipe wall thickness can be included when computing cover, drop manholes can be used to minimize cover (previously drop manholes only prevented a pipe from exceeding the maximum allowable slope) and a minimum drop depth can be specified for drop manholes. Please note that this applies to Design calculation option in GVF Convex & Rational Solvers. New Drop Structure Automated Design Constraints With this new release few changes have been made to drop structure modeling as per the requirement of users. Earlier only when manhole upstream pipe slope exceeds the conduit maximum slope and the Allow Drop Structure is set to true in design constraints so we designed manhole drop structure. With this version, now users can design drop manholes to minimize the volume of excavation. Two new design constraints, Use Drop Structure to Minimize Cover and Minimum Drop Depth, are added to node default design constraints. Same has been added to local design constraints. If both Allow Drop Structure and Minimize Cover of Node Connected Pipes are set to true, Minimum Drop Depth in design constraints will be compared with the Drop Depth when drop structure is designed at the node. Drop Depth is the difference between the upstream pipe invert at the node, when drop structure is designed and the upstream pipe invert at the node when drop structure is not designed. Please note that this applies to GVF Convex & Rational Solvers. New Hydrograph & Loss Methods Additional hydrology methods now have been added to the Hydrology alternatives which are ILSAX or time-area hydrograph methods to compute the runoff. As well infiltration losses now can be computed using ‘initial loss and constant fraction’ or ‘initial loss and constant rate’ methods in addition to the existing loss methods. The prior “fLoss” method is renamed as “Constant Loss Rate”, the methodology in calculation remains same. More information you can find in the help documentation. New Time of Concentration Methods New methods of calculating the time of concentration have been introduced in this version which are Kinematic Wave equation, Friends equation and Bransby-Williams equation. So now SS4 supports total 16 different methods to calculate time of concentration of a catchment. Each method is documented in the help documentation for further review. Storage Chambers SS4 can now model underground storage chamber systems with new component added Storage chamber as the pond type. Storage chambers have been added to SS4 as an option to the pond volume calculation. Now users can construct complex arrays of storage chambers which can be combined with other standard pond components to create a single storage entity to be used in the routing analysis. These can be accessed from the Components menu or from the properties of the pond. To know more about Storage Chambers please see the support solution below. http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/4583.entering-underground-storage-chamber-information-tn.aspx Improvement to Calculation Options Improvements to calculation options have been made for GVF Rational solver & Explicit (SWMM) solver. New field has been added to Explicit (SWMM) solver to perform Hydrogen sulfide modeling. With the changes in GVF Rational solver, now you can decide whether to include conduit flow time in time of concentration of time or not which will ultimately affect conduit size. For better understanding of GVF-Rational Solver, please see this support solution. Enhancements in Network Navigator New queries have been added to Network Navigator like orphaned SCADA elements & associated SCADA elements, in accordance with the new tool added SCADAConnect. Global Storm Events New field has been added to global storm events as average intensity. Wherein you can see the average intensity of selected storm event. It’s applicable for Time-Depth (cumulative and incremental) and Time-Intensity storm data. Inlet-only hydraulic calculations Users can now place inlets, check gutter and inlet carryover flows, and adjusts the inlet positions as necessary, before designing the pipe network. Which may be useful for doing the road drainage design before designing the subsurface piping. In earlier versions, in order to calculate the inlet capacities conduits needed to be placed, but with release inlet capacities can be calculated as can be seen in the snapshot below. This feature is only available for GVF-Rational solver. Sparkline in Flex Tables A new feature is added to the Flex Table allowing users to view Extended Period Simulation result for that element at a glance. This feature is a context menu option which can turn a results column to a Sparkline column that shows the graph of the result values over time. This feature provides a visual representation of the element results. (Please visit the site to view this video) EPS Results Table With the addition of this new field, Extended Period Simulation results can be seen for each element separately. It’s available only for EPS run in GVF Convex solver. In early versions, you had to go to Time Browser to see the EPS results. This new enhancement simplifies the results which can be viewed in a single table for all the elements. EQT curve This improvement is for the ability to support EQT tables for pond outlet structures with the SWMM solver, so tailwater effects are considered. In the past, it was basically always free outfall. There’s a paragraph about this in the help, at the bottom of the section called “Defining Composite Outlet Structures”. Surcharge-Overflowing There are some changes to is Surcharged or Overflowing fields as below: All “Ever” related results will be hidden for Rational solvers since they don’t involve time-varying. Is Overflowing? & Is Ever Overflowing are hidden for cross section nodes and channel links Is/Ever Overflowing and Is/Ever Surcharged are all hidden for transition nodes as well.

Forum Post: RE: "This node is orphaned. There cannot be any orphaned, active nodes in the model."
Hello Danielle, Could you post a screenshot of the plan view layout? You should be able to model a retention pond like the below screenshot. Ensure that the outfall is set to boundary element and is connected to the pond. If this doesn't help and you do not wish to provide a screenshot, you also have the option to privately send the model to Bentley. See below. Sharing Hydraulic Model Files on the Haestad Forum

Wiki Page: Using LoadBuilder to assign Customer Meters to the nearest pipe using taps and laterals
Product(s): Bentley WaterGEMS, Bentley WaterCAD Version(s): 10.xx.xx.xx Area: Modeling Introduction In earlier versions of WaterGEMS and WaterCAD, LoadBuilder could be used to assign Customer Meter elements to the nearest junction. With the introduction of taps and laterals in the CONNECT Edition release of WaterGEMS and WaterCAD, new tap and lateral elements, can be used to assign Customer Meters directly to the pipe. The previous workflow assigning the Customer Meters to nodes is still valid. However, LoadBuilder will not create laterals when assigning the Customer Meter to the nearest node, though the lateral can be added manually or through ModelBuilder if that is desired. The steps to assign a Customer Meter to a node is discussed in the link above. Below are the steps to assign to the Nearest Pipe using Taps and Laterals. Note: as of version 10.00.00.50, lateral link elements do not count toward your pipe limit. Steps to Accomplish These steps assume the Customer Meters are already present in the model. If you have not added them yet, you can do so manually or using ModelBuilder . This layout shows three Customer Meters that are currently unassigned to a hydraulic element. First, we will consider a case where the Customer Meter is assigned to the nearest node. Assign Customer Meter to nearest pipe Open LoadBuilder by going to the Tools tab. Click the New button in the upper left of the dialog to create a new connection. Select the Customer Meter Load Data option on the left side of the dialog. Since we are assigning the customer meter to the nearest pipe, select that option from the selections on the right, then click Next. In the next screen, you will select the Pipe Layer, Node Layer, and Customer Meter Layer. This is basically telling the program which elements the Customer Meter may be associated with. Next to the Pipe Layer option, click the ellipsis ("...") button, which will open the "Select a Layer" dialog shown above. For this case, we will choose "Pipe\All Elements," which means that all active pipes will be considered. Note: If a node is inactive, the Customer Meter cannot be assigned to that node. Only elements active through Active Topology will be considered for associated elements. In addition to selecting the Pipe Layer, you will also need to select the Load Assignment. The default setting is Closest Node, but you can also choose to weight the demand between the end nodes of the pipe, distribute the demand equally between the end nodes, or apply the demand to the farthest node. Next, click the ellipsis (...) button next to Node Layer. All node types that can have a demand applied to them are available. In this case we will choose "Junctions\All Elements". Finally, do the same thing for the Customer Meter elements. You also have the option to exclude customer meters that already have an associated element, but may not have a lateral or tap. To do this, click the "Exclude unconnected Customer Meters that already have an Associated Element." Lastly, you will want to select the option "Create taps and laterals for Customer Meters that are not connected." This will assure that the necessary elements are created to correctly associate the Customer Meters to the pipes via a tap and lateral. Click Next and see the results that LoadBuilder has calculated. Notice in the screenshot below that two of the Customer Meters are assigned to one pipe. It is possible to have more than one customer meter assigned to an individual element. Lastly, you will need to create a label for the LoadBuilder connection. You will also need to either update an existing Demand Alternative or opt to create a new alternative. Click Finish and the LoadBuilder will assign the Customer Meter to the nearest pipe, as well as create the taps and laterals to complete the connection. Reassigning taps to new pipe During the process of analyzing a model, you may need to associate an existing Customer Meter to a different pipe. If that case arises, you can use the following workflow. First, you will need to drag and drop the Tap element to the pipe that the Customer Meter should be associated with. In the screenshot below, the tap has been moved from pipe P-20 to pipe P-260. Notice the dashed line that is connected to the tap element and P-20. This means that the tap is still associate with P-20. In order to associate the tap with the correct pipe you can right-click on the tap element and choose Attach. If there are multiple taps that need to be reassigned after moving them, you there a batch tool that will do this as well. Go to the Tools tab. In the Tools section, select More > Assign Taps to Links. This tool is used to batch assign taps to pipes when there is no current association. For instance, if you manually added the customer meters, taps, and laterals, there may be no true association between the elements. The Assign Taps to Links tool will assign this. However, it can also be used to reassociate taps that are currently associated to a different pipe. To apply this, select the option "Also process taps that already have an associated link" from the Options section of the Assign Taps to Links tool. When you click OK, the tap will be reassigned to the new pipe. The tap is now associated with a new pipe. However, the customer meter is still assigned to the old pipe. You can change the association manually in the Customer Meter properties. You can also use LoadBuilder to update the association. Using LoadBuilder, you can run the existing connection. When you are on the screen where you assign the pipe, node, and customer meter layers, uncheck the box for "Exclude unconnected Customer Meters that already have a valid Associated Element." Click Next and complete the LoadBuilder process. Once you are completed, you should see the associated pipe for the Customer Meter is the same one that the tap is connected to. A note on Licensing As of the version 10.00.00.50, lateral link elements do NOT count toward your total number of pipes/links, (checked against the number of available pipes in your license .)

Wiki Page: Customer Meter Elements and the External Customer Meter Data Manager
Applies To Product(s): WaterGEMS, WaterCAD Version(s): 10.xx.xx.xx, 08.11.xx.xx Area: Modeling Original Author: Scott Kampa, Bentley Technical Support Group Customer Meter Element Customer meter elements provide a way for users to maintain customer water demand data within WaterGEMS and WaterCAD. It provides the user access to features such as element symbology and the ability to visualize customer location and assignment of demand to node elements. The new customer meter element is represented by a house icon as pictured below and the association of the element with a node or pipe is shown as a dashed line. The main steps for using the customer meter elements are entering demands for the element and assigning the customer metering element to a hydraulic model element, such as a junction. This is done by clicking on the drop down button in the “Associated Element” field from the properties grid or the FlexTable then choosing “Select Associated Element…” Note: the "Zone" field will display the Zone of the customer meter's associated element. The customer meter element can also be imported or updated from eternal data sources using ModelBuilder. More information can be found on ModelBuilder by this link: Building and updating a model using ModelBuilder The external data source should contain a label, the x-y coordinate and demand data for the new element. If the data source is a shapefile, the spatial data is included already, so x-y coordinates are not needed. Demands can be entered manually by entering values in the property grid, the customer meter FlexTable, and the Demand Alternative under the Customer Meter tab. Demands from a customer meter element must be assigned to the associated hydraulic modeling element in order to be used in the calculations. The demand control center is not used for the customer meter element because there can only be a single demand and unit demand for a customer meter. Importing Customer Meters with Loadbuilder LoadBuilder can be used to assign the customer meter element to the hydraulic modeling element using one of the allocation methods located within the “Customer Meter load data” in the first step of the LoadBuilder process. The different methods that can be chosen are, "Nearest node", "Nearest pipe", or “Customer Meter Aggregation”. The "Model Node Layer" will usually be set to ‘Junction\All Elements’, but it can also be any selection set of node elements that have “Demand (Base)” as a property. The "Customer Data" is usually set to Customer\All Elements although it can also be any selection set of customer meter elements. If the customers are being assigned based on nearest pipe method, in addition to specifying the Model Node Layer and Customer Data, the user must also specify the Model Pipe Data which identifies the pipes to be considered. This enables the user to use a selection set which can ignore large transmission mains with no customers. Note : - For more information on connecting customer meters to pipes with taps and laterals, see this article . - When using Loadbuilder to assign customer meters to junctions, the user should update the existing Demand alternative rather than create a new one. If a new Demand alternative is created, the demand data imported through ModelBuilder will be lost. Typically, customer meter elements are not directly used in hydraulic calculations so there are no hydraulic results for them. The user should find results in the node to which the customer element is associated. However, starting with the CONNECT Edition release of WaterGEMS and WaterCAD, results fields for hydraulic grade and pressure have been included for the customer meter element. If you want to include these results in the customer meter, open the Calculation Options and change the property "Calculate Customer Results?" to True. When you compute the model, you will see results for hydraulic grade at the current time step, as well as maximum and minimum results across the model run. If you are using WaterGEMS/WaterCAD V8i SELECTseries 6 or earlier, hydraulic results will not be directly available. External Customer Meter Data Manager A new External Customer Meter Data manager have been added so that external source data can be added to the Customer Meter element. This allows the user to see detailed information about the location that the Customer Meter element represents. Similar to ModelBuilder, the user can select from a number of source file types, such as database files and Excel files, and import the data into the External Customer Meter Data manager. This can be important in keeping track of demand information that will be applied to the Customer Meters. For a free Webinar on using the Customer Element, click this link .

Wiki Page: How can I reduce the number of pipes in my model?
Product(s): WaterGEMS, WaterCAD Version(s): 08.11.XX.XX Problem How can the number of pipes be reduced in a WaterCAD or WaterGEMS model? Problem ID#: 74797 Solution To reduce the number of pipes in a model try to combine pipes that have equivalent diameters and roughnesses. If you have access to Skelebrator (Tools > Skelebrator) in WaterCAD/GEMS if you have that feature available to you. See more on Skelebrator in the articles linked to further below. If you have hydrants , considering placing them on the main pipeline, and model the lateral losses using the imbedded properties in the hydrant (rather than adding the extra lateral pipe. You can also use Laterals and Customer elements to assign demands along the length of a pipe instead of creating extra nodes (which split the pipe). As of version 10.00.00.50, lateral link elements do not count toward your pipe limit. Furthermore, you can also use isolation valves instead of valve node elements (like GPVs or TCVs) to model valves, as the isolation valves do not split the pipe.

Forum Post: RE: Modelling Inlet Works of a Treatment Plant
Hello Hugh, Are you using SewerCAD or SewerGEMS? With the GVF-Convex solver, it is assumed that pumps will be connected to wetwells, for outflow. As you mentioned, you also cannot use a conduit control structure to divert flow. You also cannot model a split via multiple pond outlet structures with the Convex solver (see more here ). You would need to create a diversion rating table to do this. See the following article: Modeling a flow split (diversion) with the SewerCAD or StormCAD numerical solver With that said, typically the SewerCAD solver (or product) is used to design the wetwell such that it would not overflow. If you're looking to see if a wetwell is undersized, you would check if the wetwell HGL reaches the maximum level and react accordingly. If you need to actually quantify overflow, the SewerGEMS product (with either the Implicit dynamic or Explicit (SWMM) dynamic solver) would be the best choice. With this, overflow can be modeled in a few different ways. See article: How do I model wet well overflow?

For the HEC-22 2nd edition it's fine to use either the HG or the EG option, although technically speaking the EG option is more correct. This is because the head loss by definition is the energy loss. When using the HEC-22 3rd edition, however, an engineer should only use the EG option for a structure loss method because HEC-22 specifically states that only the EG should be used when computing structure loss. Plunging Flow In 2 nd ed., the largest incoming invert is considered. In 3 rd ed. it’s done based on each pipe. The 2 nd ed. refers to center line of the outflow pipe whereas the 3 rd edition ignores the outflow pipe In the 2 nd ed., plunging coefficient is statically declared, in 3 rd edition it is a proportion of plunging flow to all incoming flow. In the 3 rd ed., there is a ceiling put on maximum plunging depth of 10 * diameter. In the 2 nd ed. there’s a comparison of incoming pipe invert to structure invert, in the 3 rd it is compare of incoming pipe invert and structure energy level. Benching New benching classification titled “Improved” (both 2 nd and 3 rd editions) Benching is interpolated in the 3 rd edition and not in the 2 nd An “IsSubmerged” condition is defined for a lower threshold in the 3 rd Bend Loss In the 2 nd ed. it is folded into an initial headloss term In the 3 rd ed. it is a weighted composite loss from each incoming pipe Initial Headloss In the 2 nd ed. it is computed with bend angle and structure equivalent diameter In the 3 rd ed. it is an inlet or outlet control that governs this Entrance and Exit Losses (most significant component of 3 rd ed. junction losses) These are transitions between the node structure and the outflow pipe Exit losses are only computed in the 3 rd edition 3rd ed. computes each exit loss for each incoming pipe. 2 nd ed. lumps entrance, structure, and exit loss considerations into one structure loss result and uniformly applies it as tailwater for all incoming pipes. Profile Enhancements Addition of Exit, additional, and entrance losses is displayed from pipe to pipe As of the CONNECT Edition (10.00.00.40), with the Explicit (SWMM) solver, there is a separate result field for the Entrance loss component, and all other losses are included in the field "Total additional structure energy losses", along with the total structure energy loss result. These can be seen in the "Results (HEC-22, Third edition)" section of the manhole properties, or in the manhole flextable. With the GVF-Convex and GVF-Rational solvers, there are additional result fields, for all the different components.

Forum Post: RE: HEC-22 3rd Edition Dealing with Entrance/Exit Headlosses
Hello David, See the help topic called "Headloss - HEC-22 Energy (Third Edition) Loss Method" and the related sub-topics. They explain the different components of the total loss for a structure with the HEC-22 Third edition structure loss method and the three primary calculation steps. This includes entrance and exit losses for the conduits, so you should not need to account for these in the conduits. The following article also has some information on this subject: What are the differences between HEC-22 3rd edition and HEC-22 2nd edition? Currently, with the Explicit (SWMM) solver, there is a separate result field for the Entrance loss component, and all other losses are included in the field "Total additional structure energy losses", along with the total structure energy loss result. These can be seen in the "Results (HEC-22, Third edition)" section of the manhole properties, or in the manhole flextable. For a special note on the exit loss, see the topic "HEC-22 Energy (Third Edition) - Exit Loss" - this loss can be seen in profile view. With the GVF-Convex and GVF-Rational solvers, there are additional result fields, for all the different components. The "Headloss" result field accounts for the entrance loss and "total additional" losses. Exit losses would be separate from this. If in doubt, you should also be able to see the different component loss/drops in profile view.

Wiki Page: Can a model be saved down or back to an older version?
Applies To Product(s): WaterGEMS, WaterCAD, HAMMER, StormCAD, SewerCAD, CivilStorm, SewerGEMS, PondPack Version(s): 10.00.xx.xx, 08.11.xx.xx Area: Modeling Original Author: Dan Iannicelli, Bentley Technical Support Group Question Can a model be saved down or back to an older version? How can I send my model to a user who has an older version? Can it be "saved down"? Solution A model cannot be saved 'down' and most versions are not forward compatible. For example, if you've created and saved a model in WaterGEMS V8i SELECTSeries 6, a user with an earlier version of will not be able to open it. New releases of the programs have introduced many new element types and features, which will often not be interpreted by an older version of the product. Another reason is that the structure of the database files used to store model data (the 'schema') changes between major versions to accommodate improvements and new features. The older versions cannot interpret the new database format. Note: our products are however backwards compatible, in that you can open a model saved in an earlier version. Below are the options available to resolving this issue. Option 1: Upgrade The recommended solution is to upgrade to the latest version of the software, or at least the version used to modify the model you want to open. Downloading Haestad / Hydraulics and Hydrology Software Option 2: Export to EPANET (Water) or EPA SWMM / LandXML (Storm and Sewer) If the user is not able to upgrade to your version, the best workaround for the Water products (HAMMER, WaterCAD, & WaterGEMS) would be to export the model to the standard EPANET format (File > Export > EPANET). This format can be opened in most older versions (File > Import > EPANET). For example in older v8i versions, you can import EPANET via File > Import > Network. Note that there are limitations with this method such as only being able to export one scenario, and other items described in this wiki article . The best workaround for SewerGEMS and CivilStorm would be to export the model to the EPA SWMM format (File > Export > SWMM v5). After that the SWMM file can then be opened by most older version of the software (File > Import > SWMM V5). As with the EPANET for the water products, you may also run into some limitations or have the potential to lose some information in the process of the export/import. In SewerCAD and StormCAD, you can export the model to the LandXML format (File > Export > LandXML) and import the LandXML file into the older version of SewerCAD or StormCAD. Option 3: Export to Shapefiles Another workaround would be to export all elements in your model to shapefiles and then import those shapefiles with the older version of the software using ModelBuilder. The first thing you need to do if you're using this method would be to make sure all your FlexTables have all the information you input for the properties of each element and then export each element to Shapefiles. Export your elements to Shapefiles is described in the following wiki: Converting your model elements to Shapefiles After you do this you would need to use the ModelBuilder tool in the older version of the software (Tools > ModelBuilder) to import all those elements back in. Using ModelBuilder to construct a network is described in this wiki found below and there is also information in our help documentation on how to use ModelBuilder: Building and updating a model using ModelBuilder This method can take some time to work through. It will assure the data is imported accurately. However, each scenario will need to be done separately.

Forum Post: RE: Conversion of Water Gems file from V8i Select Series 6 to Select Series 4 (or) 5
Hello Thangaraj, WaterGEMS versions are not forwards compatible. As we release major new versions (such as between V8i SELECTseries 4, 5 and 6), they have included updates to the database structure and new elements/components that could not be interpreted by older versions. See related article for more explanation, and options: Can a model be saved down or back to an older version?

Wiki Page: Do the interpolation schemes used by HAMMER satisfy the Courant stability condition?
Applies To Product(s): HAMMER Version(s): V8i, CONNECT Edition Area: Modeling Original Author: Scott Kampa, Bentley Technical Support Group Problem Description Do the interpolation schemes used by HAMMER satisfy the Courant stability condition? Solution Courant stability criterion is not relevant to the method of characteristics (MOC), but rather applies to explicit finite-difference solutions of hyperbolic partial differential equations. (The Courant condition imposes a maximum time step as a function of the spatial step and wave speed.) In MOC, there is no theoretical limit on the size of the time step for the sake of stability; practical limits arise on account of accuracy concerns due to complex boundary conditions at nodes and nonlinear frictional losses.

Forum Post: RE: Wiki on how to get SewerGEMS and WaterGEMS Connect Edition to work with Civil3d?
Thank you guys for the links! I appreciate it. I think, to make it simple is to try and not bring the aerial in at this time. Just draw it up on CAD then bring it over as the links state below and trace over. Trying to bring an aerial not tied to the ground surface beforehand gets a little tedious to line up correctly. Will you guys at some point subscribe to say Google Earth or Bing Maps so that if we have a coordinate system in place that it will bring up the aerials live if necessary in that area? I think it would be very beneficial

Applies To Product(s): WaterGEMS, SewerGEMS, CivilStorm, StormCAD, PondPack, SewerCAD, HAMMER, WaterCAD Area: Other Original Author: KATHY WIGGINS, Bentley Technical Support Group Problem Error using TRex tool in WaterGEMS V8i Error message reads: Could not load file or assembly 'Bentley.Geometry.2.0, Version=2.0.0.0, Culture=neutral, PublicKey Token=4bf6c96a266e58d4' or one of its dependencies. The system cannot find the file specified Solution This problem can occur if WaterGEMS does not recognize the watergems.exe.config file properly, which is located in the WaterGEMS installation folder. First, try reinstalling Microsoft .NET Framework 3.5 and MSXML version 6, from Microsoft.com. If this does not help, please try the following: 1) Close WaterGEMS and/or ArcGIS 2) Open Windows Explorer and browse to the WaterGEMS installation folder. By default, this will be "C:\Program Files\Bentley\WaterGEMS\" 3) Within the WaterGEMS folder, open the "SharedAssemblies" subfolder, where you will see several .dll files 4) Copy all these files into memory: highlight all of the .dll files, right click and choose "copy" 5) Paste the files into the installation folder: browse back to the main "WaterGEMS" folder, right click and choose "paste". 6) Reopen WaterGEMS and try Trex
