Applies To Product(s): WaterGEMS, WaterCAD, StormCAD, SewerCAD, SewerGEMS, CivilStorm, HAMMER Version(s): V8i SELECTseries 2 + Original Author: Scott Kampa, Bentley Technical Support Group Overview The purpose of this technote is to briefly review the methodology for setting up a formula-based User Data Extension. Additional information can be found in the Help section for the program. Background User Data Extensions (UDX) have been a feature available in the water and waste water products for some time. With the release of SELECTseries 2 builds of the software, a new 'Formula' ability was added to give extra flexibility to the user. This feature will allow the user to calculate results that the programs might not otherwise generate and display these results in the element properties or FlexTables. NOTE : a formula-derived user data extension currently only evaluates at a given timestep. Meaning, you currently cannot perform functions against time-series data, such as the maximum, minimum or average value of a result field over the simulation duration. General Information on User Data Extensions User Data Extensions allow the user to create new fields for use in reporting, graphing, or data analysis. For example, you can add a field for keeping track of the date of installation for an element or the type of area serviced by a particular element. The UDX dialog can be accessed directly by going to Tools > User Data Extensions or by selecting the UDX icon from the toolbar. Selecting either of these will open the User Data Extension dialog. There are a number of data types available. These include integers, real (or any fraction decimal number), text, date/time, boolean (true or false), and formula. There is a label field to allow the user to give the UDX a unique name so that it can be easily viewed in the element properties or FlexTables. With real and formula UDX fields, the user must also enter Dimension, Storage Unit, and Numeric Formatter. To create a UDX, highlight the element and select the New icon. The section on the right will fill in with default data. As this technote is related to formula-based User Data Extensions, change the Data Type to “Real (Formula)”. When this is completed, the Units section will appear. Enter the appropriate Dimension, Storage Unit, and Numeric Formatter for analysis you will be conducting. You should also change the label to something recognizable for the analysis. Once you have done, select Okay. Note: Once you select Okay, some fields, such as Data Type, Dimension, and Storage Unit, cannot be changed or edited. The formula itself can still be edited though. Formula-based User Data Extensions Bentley's Hydraulics and Hydrology products give a wide range of results that are generated after the computing a model. In most cases, these results are sufficient for analyzing and reporting on a system. However, there are times when a user may want to see a set of results that are not available in the program. It was for cases like this that the formula-based User Data Extension was developed. Note: You cannot create a formula that uses properties from more than one element type, and the results of a formula UDX are only evaluated at a given timestep (you currently cannot find the max/min/average for example, of a result over time) The formula-based UDX allow the user to generate new results based on the data already calculated after computing the model. The basic steps below are universal, with only the element types and available properties differing depending on the product. The example below will be using WaterGEMS. Let us say that you want to display the percentage of pressure head compared with the calculated hydraulic grade for the junctions in a WaterGEMS model. To begin, open the User Data Extension dialog. Create a new UDX by selecting the New icon at the top of the dialog. Change the label to something recognizable to these results and change the Data Type to “Real (Formula)”. Since the result will be a percentage, change the Dimension field to “Percent”, the Storage Unit to “%”, and Numeric Formatter to “Percent”. Next, click in the Formula cell. An ellipsis (...) will appear. Click this to open the Formula dialog. In the upper left is a list of all available properties for the junctions. The list is in alphabetical order. The same properties are accessible through the “>” icon above the list. In the upper right are all of the mathematical functions available. The empty window in the lower part for the dialog is where the formula is built. To move a property to the lower window, simply doubleclick the name. It will then appear in the window. Note that the appearance is not the same as the property list; the window shows the Access database table name for that property. To include a simple math function, like multiplication or subtraction, click the corresponding button. For the geometric or trigonometric math functions, doubleclick the name to include in the formula. In the example where we want the percentage of the pressure head compared with the calculated hydraulic grade, first select the “(“ icon. Next, find “Pressure Head (ft)” in the properties list and doubleclick. Next choose the divide icon, then the “Hydraulic Grade (ft)” property, and then the “)” icon. Since we want this as a percent multiply this by 100. Once completed, select 'OK' to return to the User Data Extension dialog. Click 'OK' again to save the UDX. *Note: Many features, including the Data Type, Dimension, and Storage Unit, cannot be changed or edited after selecting 'OK'. Viewing Results Since the results are saved as user data extensions, you can view the results in either the element properties or the FlexTables. After computing the model, double click on a junction to open the Properties dialog. Find the “User Defined” section. This is where the formula UDX field will be located and, since the model was computed, you should see the results. To see the results in the FlexTables, open the element FlexTable (View > FlexTables, for instance). With the FlexTable open, select the Edit icon. Scroll through the list on the left to find the UDX field. The list is in alphabetical order. Select the 'Add' button and it now appears in the list on the right. Click 'OK' to return to the FlexTable. The statistical analysis results should now be available. This data is also available for results presentation in graphs and data tables. You will also be able to created color coding and annotation through Element Symbology once the User Data Extension is created. Exporting UDX If you want to use the User Data Extensions that you have created, you can export them to a .XML file for use in another model. To do this, click the Export to XML button in the upper left. This will allow you to save the UDX as an .XML file for later use. To add the exported UDX's into a new model, open the User Extension Manager in the new model. Then click the Import button in the upper left and browse to the .XML file with the User Data Extensions you wish to use. The UDX's will then appear in the model for use.

Problem ID#: 90398 Solution The Total Dynamic Head is basically the pump head - the head that the pump adds which overcomes both the "static head" (difference in upstream/downstream boundary conditions) as well as the "dynamic head" which is the headlosses in the pipes between. If you are looking for just the dynamic portion, you would have to find the difference in elevation between the upstream and downstream boundaries (wet well, outfall, etc.), then subtract that from the total pump head.

Wiki Page: Automated design with different conduit materials and shapes
Product(s): SewerCAD, StormCAD, SewerGEMS, CivilStorm Version(s): 08.11.02.XX+ Area: Libraries/Catalogs Problem When running automated design, the program only picks pipes with one particular material and does not pick higher diameter pipes that may have a different material. Automated design not picking other shapes or materials besides the initial ones. Applies to: Design mode with the GVF Rational (StormCAD) or GVF Convex (SewerCAD) numerical solvers. Problem ID#: 60859 Solution Currently, the automated design routine only designs the sizes and assumes the shape and material that was initially set in the conduit. This is due in part because it is unlikely that you would not already know the shape and material of your pipe. Shape and material can be adjusted after automated design. If you have different materials for different size pipes of the same shape, you'll need to choose the same material for all your catalog conduits (the one used as the initial pipe material), run automated design, then change the material field appropriately based on the designed diameter.

Wiki Page: Is it possible to apply a filter the Sanitary Load or Inflow Control Center by attribute or by selection set?
Applies To Product(s): SewerCAD, SewerGEMS, CivilStorm, StormCAD Version(s): 10.00.xx.xx, 08.11.xx.xx Area: Modeling Original Author: Jesse Dringoli, Bentley Technical Support Group Problem Is it possible to apply a filter the Sanitary Load or Inflow Control Center by attribute or by selection set? Problem Number: 35188 Background Typically, you would be able to filter elements in the element FlexTables . However, since the Sanitary Load Control Center and the Inflow Control Center can have multiple entries for a single element, it is not possible to filter the FlexTables by loading data. It is possible to filter like this in the control center dialogues. This allows the user globally edit only certain elements, while leaving the original values set as they were. In the CONNECT Edition of the product, you can open the control centers by going to the Home tab and choosing Loading > Sanitary Load Control Center or Inflow Control Center. In the V8i releases of the product, go to Tools > Sanitary Load Control Center or Inflow Control Center. Filtering by Attribute Once you are in the Sanitary Load Control Center or Inflow Control Center, choose the Options button, then select Filter > Custom. You can then choose the attribute you want to filter by from the pulldown menu in the Attribute column. Then you would select the Operator and the value you want to filter by. Filtering by Selection Set First, a selection set would need to be created. Once that is done, double-click on the selection set to highlight the elements in the drawing. Once this is done, open the Sanitary Load Control Center or the Inflow Control Center. Next, click the Options button and choose Filter > Current Selection. This will filter the table by only the elements in the selection set and allow you to make necessary changes. If you are using version 08.11.02.75 and earlier: The steps above will not work if you have older version of the storm-sewer products. Below you can find the steps to do this in these older versions. 1. Go to View > Selection Sets and double-click the selection set in question to select the element in the drawing 2. Go to View > FlexTables, right-click the manhole predefined FlexTable and choose "Open on Selection" 3. In the Manhole table, click the Options button and click "Relabel" 4. Choose "Append" as the operation and type in a unique string of characters for the "Prefix" field. For example, "SELECTIONSETA" 5. Click OK, close the manhole FlexTable, and open the Sanitary Load Control Center 6. Click Options > Filter > Custom. Choose "Label" as the attribute, "Begins With" as the operation, and "Value" for the Prefix 7. Click OK. You will now only see loads for manholes that are part of your selection set. 8. When done with your edit, you can restore the manhole labels by reopening the "Relabel" tool in the manhole table, choosing "Replace" as the operation and then your prefix in the "Find" field. "Replace with" will be blank, since you will essentially be deleting the prefix you had added in step 4.

Justine, Select Components > Pump Definition and enter the pump curve data here. If you are just doing a hydraulic calculation, you only need enter the head characteristic curve. If you are also doing energy calculations, you need to enter the efficiency curve as well. Then in the pump element property grid for that pump, pick that curve in the drop down for Pump Definition.

Wiki Page: Can I add exit losses to an outfall in storm-sewer products?
Product(s): Bentley SewerGEMS, StormCAD, CivilStorm Version(s): 08.11.XX.XX Area: Layout and Data Input Problem Can I add exit losses to an outfall in StormCAD? Problem ID#: 42163 Solution There are no losses through the outfall node element, this is as-designed. The losses will have to be added to different prior structures like manholes, catch basins etc. For example, if the system ends at the outfall, where in reality there's a culvert, then it will need to be modeled with the headwall and conduit designed as a culvert, with losses being considered at the manholes.

Wiki Page: Modeling Reference - Headwalls
Applies To Product(s): CivilStorm, SewerCAD, SewerGEMS, StormCAD Version(s): 10.00.xx.xx, 08.11.04.xx and later Area: Modeling Original Author: Sushma Choure, Bentley Technical Support Group Introduction The new element which is introduced with the release of SS4 is the headwall. This technote explains about general structure of headwall as an element. The Headwalls are generally concrete or masonry retaining walls, which are placed at the outlet side of a drain or culvert. Headwalls should be designed as such by considering factors such as earth pressure, loading and soil properties. The Headwall element has been added in SS4 in order to support subsurface utilities projects allowing users to directly analyze and design these structural elements without having to insert inlet and/or cross-section elements as proxy hydraulic elements. The Headwall element is available for modeling in the layout toolbar as shown below. Headwall node within the Standalone Layout Toolbar A headwall node that is the Start Node to a conduit will be laid out as a mirror image to headwall node that is a stop node. A headwall can only be designed for a closed conduit and only a conduit link can be used to model a culvert. It is not possible to connect two conduit links with a headwall node during layout. By hydraulic convention, culvert entrances usually have end-treatments that correspond to headwalls at the entrance and endwalls at the outlet. But we will refer to all end treatments, regardless on upstream or downstream location or structural aspect as Headwalls. While setting up the headwall in the model you need to define the referenced culvert in the properties of the headwall as seen below. A conduit that is declared to be a culvert link may have a headwall node at either end. Conduits can be set as culverts by changing "Is Culvert?" property to 'True' in the properties of the conduit. You may model projected or mitered end treatments on a culvert link with connection to a cross section or outfall node. Different possible combinations of headwalls can be seen below. If you attempt a configuration that is not permissible, you will get user notification for that. You may model projected or mitered end treatments on a culvert link with a connection to a cross section or an outfall node. Different possible combinations of headwalls can be seen below. If you attempt a configuration that is not permissible, you will get user notification for that. More Valid Configurations: Culvert with channel links Some Invalid Configurations, yet possible to layout. User notifications expected Headwall Property Grid: Basic Attributes The following attributes of a headwall node are visible in the headwall property grid. Headwall Property Grid Culverts in SS3 & in SS4 Culverts in SS3 used to be designed using a cross section node at the end. Culvert inlet coefficients could be specified through conduit properties. With release of SS4 headwalls can be designed for the culvert at one end or at both the ends. A comparison can be seen in the screenshot below. Culverts in SS3 & Culverts in SS4 The headwalls are the end treatments of the culverts. If you need to model a headwall there has to be an adjacent culvert for that. Set the 'Is Culvert?' to 'True' in the properties of the conduit and then upstream and downstream headwalls in the physical properties of culvert (see screenshot above). Culvert inlet Coefficients: In previous software releases you could reference an entrance loss and other Form 1 and 2 coefficients by selecting a culvert inlet coefficient engineering library data instance through the conduit property grid as seen below. Selection of Culvert Library Data from Conduit Property Grid in Bentley SewerGEMS SS3 Starting with SS4, element manager called the 'Culvert Inlet Coefficients' dialog is accessible from the Components menu, appearing just after Conduit Catalog. The manager dialog is similar to Conduit Catalog manager, including sync capabilities to the Culvert Inlet Coefficients type of engineering library data. The headwall section properties can be set through the headwall property grid & as well as the conduit property grid. The Culvert Inlet Coefficients manager dialog has two label columns: Label and Barrel Shape. Mock-up of Culvert Inlet Coefficients dialog All the attributes of culvert inlet coefficients engineering library data are mirrored and made available for editing in the right side of the dialog. From a headwall property grid, you can reference from the culvert inlet coefficient manager by selecting […] from inlet description. This function is similar to selecting a conduit catalog reference. A non-editable preview of referenced support element data values is displayed in the corresponding fields in the headwall property grid. Conduit Property Grid & Headwall Property Grid in SS4 The culvert barrel shape field reflects as a read-only value of the downstream conduit’s shape if the headwall node is a start node. It reflects the value of the upstream conduit shape if it is a stop node. The read-only 'Is Inlet?' attribute is 'True' if the headwall node is a start node. It will be set to 'False' if the headwall node is the connected downstream node of the culvert link. Boundary types of Headwall Inlet Intermediate Free outfall Discharge to Pond Pond Outlet Headwall with no upstream connections- Inlet A headwall node can be the most upstream node in a gravity sub-network, similar to other gravity network nodes. In this case, a derived result field 'Boundary Type' will have value of 'Inlet'. This value is presented in headwall property grid when it detects there is no incoming link. The default value of this attribute is 'Intermediate', if headwall is an intermediate element in the model. When the node has a state of 'Inlet' or 'Outlet', the 'Cross Section' related attributes are visible in the property grid but they will not be validated, you will get a user notification – Cross section dimensions are ignored. Conduit attributes are used instead. Headwall with no downstream connections – Free Outfall A headwall node can be the terminal point of a gravity sub-network, in place of an outfall element. In this case, a derived result field "Network Boundary Type" has value of "Outlet". This value is presented in headwall property grid when it detects there is no outflow link. Headwalls as end nodes for a channel By setting the headwall property field "Has Cross Section?" to True, you can place a channel between two headwalls. When you set this to True, you will be able to enter the start and/or stop properties for an irregular or trapezoidal channel. Headwall as an alternative to a Pond Outlet Structure In previous releases, only the Pond Outlet Structure node modeled the downstream connections in the network from a pond. But you may now model the Pond outflow through a headwall node and culvert link. When headwall node is not a stop node (the headwall node has no incoming channel or conduit link), When a headwall node is at an upstream end of the network with no upstream elements, then the upstream pond can be connected to headwall, which will act as pond outlet structure, if required. A dashed line connected to pond will be drawn, with the same behaviour as a pond outlet structure node. In this configuration, the 'Boundary Type' is set to 'Pond Outlet'. Valid configuration: Headwall instead of a Pond Outlet Structure. Headwall empties to a Pond If the headwall node has no outgoing link, then user can select the 'Boundary Element' option, so the Boundary Element field can be used from the headwall property grid to select a neighboring downstream pond. This mimics the function of an outfall to pond connection. In this configuration, the 'Boundary Type' is set to 'Pond Inlet'. Property grid state for Headwall when selecting a Pond as a Boundary Element. Valid configuration: Headwall empties to a Pond. Profile View: The headwall element can be seen in the profile view as below, wherein the drop in the HGL is seen in the conduit. Limitations of Headwall: At a headwall node you cannot have: J unction headloss Locally injected sanitary flows Incoming conduit (closed Pipe shape) links Outgoing conduit (closed Pipe shape) links Headwall elevations are not modified during Design run Headwalls cannot be designed using Explicit SWMM solver Velocity Head (In-Governing), because multiple incoming pipes are not permitted Elevation (Invert in 1, 2, 3…), because multiple incoming pipes are not permitted Sample File You can download the sample file of H eadwall model from the below mentioned link. http://communities.bentley.com/products/hydraulics___hydrology/m/hydraulics_and_hydrology_gallery/270016.aspx

Forum Post: RE: Inlet Control for Storm Drains in StormCAD
Hello Steve, StormCAD solves the entire network using a backwater analysis, generally starting at the outfall and working upstream to calculate the flow profile. When a supercritical condition occurs, a frontwater analysis is performed (starting at the upstream end and working down) and you may end up with a hydraulic jump. You can check this in the Profile Description field. More on this here: How are the profile descriptions derived in SewerCAD's GVF-Convex solver or StormCAD's GVF-Rational solver? Are you saying that the pipe has more capacity than the flow through it yet the HGL is near or above the top, or are you saying that the flow through the pipe is more than the capacity, yet the HGL is below the top? Either case can occur, because the capacity figure shown in the pipe is based on normal depth and since the a gradually varied flow profile is computed for the whole network, a pipe may not necessarily be flowing at normal depth. More on that here: Why does the profile for the system appear to be at odds with the results for the capacity? So, a pipe in theory may not have enough capacity, but based on the flow regime and pipe length, it may not be surcharged. If you need to only analyze one culvert, specifically for inlet control, you may want to look into CulvertMaster . This solves one culvert at a time and will report both the inlet and outlet control headwater: If you want to prevent downstream tailwater effects from influencing the culvert results in StormCAD, you could use the Headwall element with a large downstream conduit connected to an outfall node set as free outfall. I'm not certain what you mean by "what HW condition is most suitable", but based on the upstream flow and properties of the headwall, StormCAD will compute the "headloss" across the headwall and therefore provide the headwater and resulting flow profile.

Forum Post: RE: Check Valve Element Closure Downstream The Pump
Hello Mohammed, Are you using WaterCAD/WaterGEMS, or HAMMER? Are the results you refer to for a transient analysis in HAMMER, or a steady state/EPS simulation? Assuming you're referring to a transient simulation in HAMMER, the results can indeed be very sensitive to the model arrangement. With the check valve in the pump, the closure occurs inside the pump node, whereas if you use a check valve node downstream of the pump, it introduces a length of pipe between the check valve and the pump, so depending on the configuration of the pump, waves from the closed check valve can interact with the pump. It is typical for results directly next to the pump to be sensitive when closed off, as the waves will reflect and interact very quickly. Furthermore if you used a very short pipe between the pump and the check valve, it may be adjusted significantly depending on the wave speed and timestep. You can read more about that in this article: Understanding length/wave speed adjustments and their impact on results Also note that when using the check valve node element, you have some additional options to define the behavior of closure, which are not available with the check valve built into a pump. The pump check valve assumes instant closure whereas the check valve node can have a slow opening or closure time. You can read more about the differences between the different ways to model a check valve in HAMMER in this article: Modeling Reference - Check Valves
