Steps to Resolve It is possible to set up a prototype for an element to use a set of default values that you want to use for a model. To do this, go to View > Prototypes. Highlight the element you want to create a prototype for and select New. This will create a new Prototype. You can rename this if you wish. Doubleclick the new prototype to view the properties. Enter a new value for any field that you want to change the default values. In the Prototype manager, make sure that the prototype is set as the current value. When you create an element of this type, it should now use the values from the prototype. You can create more than one prototype for a given element. If you do this, make sure that you have the correct prototype set as the current one. This is done either by highlighting the prototype and selecting the "Make Current" button, or by right-clicking on the prototype and selecting "Make Current."

Wiki Page: Importing Loading Information Using Modelbuilder [TN]
Applies To Product(s): Bentley SewerCAD Version(s): 08.11.00.48 and above Environment: N/A Area: Data Import/Export Subarea: N/A Original Author: Jesse Dringoli, Bentley Technical Support Group Overview This TechNote describes the process by which a user can import sanitary or inflow loading data using Modelbuilder. It assumes Bentley SewerCAD V8 XM will be used, but the process is the same for Bentley SewerGEMS V8i. Background In SewerCAD, loading information can be entered as a Hydrograph (flow vs. time), Unit based (unit type and count), Pattern based (base flow and pattern) or fixed load (single base flow, held constant.). Loads can be categorized as either sanitary dry weather or inflow wet weather. If your loading data is in an Excel spreadsheet and you have a field that contains labels that match your SewerCAD model's manhole labels, you can use the Modelbuilder feature to import them. For example: Note: if your loading information is contained within shapefiles , you will need to use the Loadbuilder tool to import them, based on the spatial information. This is outside the scope of this Technote. If you attempt to import the loading information using Modelbuilder, you may end up with the following unexpected result: As you can see, these pattern-based loads and Unit loads did not import correctly. The correct patterns/unit loads were not assigned and the load has imported as a Sanitary Hydrograph load type. Because of this, the base flow and unit count are ignored. There are two reasons why this has happened: The patterns must be defined ahead of time, under Components > Patterns. Modelbuilder will not automatically create patterns; it is simply linking the data in your source file (the pattern labels) with the pattern field. If the patterns are not defined yet, then a matching selection will not be found and you will get the above warning. The same applies to the unit load label. Your unit load (for example, ‘Residential', representing 100 gpd per person) must also be defined ahead of time before the unit count can be imported into your manholes. Since a sanitary load can be a Hydrograph, Pattern-based, or Unit load, the user must specify which of these load types is being imported, in addition to the information already in the spreadsheet. Without specifying this Load Definition, the program will import the load as the default type, which is Sanitary Hydrograph. Properly Importing your Loads in Modelbuilder Note that when you import loads using this process, they will override any previous loads assigned to those manholes included in the spreadsheet. So, this process cannot be used to 'update' an individual load for manholes who have multiple items in the sanitary load collection. All of the loads that should be present for a particular manhole should be included in the spreadsheet when using this process. Note: It is possible to have two different types of unit loads applied to a single manhole, but all loads will need to be added at the in the same ModelBuilder connection. First you must define your patterns (if importing any pattern-based loads). Go to Components > Patterns. Create a new hydraulic pattern and enter the starting multiplier along with the table of time and multiplier: To import patterns using Modelbuilder , have a look this support solution. Ensure that the labels for your patterns match the ones in the source file that contains the loading data. If you need to import any unit loads, you will then need to define them, under Components > Unit sanitary loads. Next, open your source data file and add a new field called "Load Type". For each row of data, you will need to type in the corresponding load type. For sanitary loads, they must be entered exactly as follows (spelling and capitalization): Sanitary Unit Load Sanitary Pattern Load Sanitary Hydrograph For manhole Inflow loads, they must match the following: Pattern Fixed Load Hydrograph Load Your source file may look like this: Note : C omposite loads (more than one load per manhole) will also work. Meaning, you can have multiple rows with "MH-1", but with different loads. For example, MH-1 might have both a pattern load and a unit load, or perhaps it might have two different types of unit loads. Next, start a new Modelbuilder run by going to Tools > Modelbuilder and clicking the white paper icon. Select your Data Source type and then the file itself. Click the check box next to only layer or worksheet that contains the data. You can click "Show Preview" to check the data in the layer selected: Click Next. On the next page, uncheck all spatial/creation/deletion options. This is because we are updating elements, not creating or deleting them. Click ‘Next' to display the field mappings. First, click on the layer on the left side and select "Manhole, Sanitary Loads" as the "Table" type. Note that if you need to bring in one of the Inflow load types, you will need to select "Manhole, Inflow (Wet) Collection" as the table type. If you need to bring in a "Fixed Load" inflow load type, your source file will only need to include a column for the flow and for the load type (‘Fixed Load'.) For the "Key/Label field", select the column name that contains the manhole labels. On the bottom of this window, each of your fields will be displayed. You will need to click each one and link them to the corresponding SewerCAD field. Note: If the label in the spreadsheet does not match the label in the model, a new element may be created. Be sure that the labels in the source file match the model labels. ‘Base Flow' - the base flow field associated with a pattern-based load (Make sure you check your units!) ‘Index' - This is used for hydrograph loads (beyond the scope of this TechNote) ‘Load Definition (ID)' - the internal ID number of the load type. This does not need to be used. ‘Load Definition (Label)' - the field containing the type of sanitary load you are importing (described above) ‘Loading Unit Count' - the count field associated with a unit load ‘Pattern (ID)' - the internal ID number of a pattern. This does not need to be used. ‘Pattern (Label) - the field containing the name of the pattern associated with a pattern-based load ‘Unit Sanitary Load (ID)' - the internal ID number of the unit load. This does not need to be used. ‘Unit Sanitary Load (Label)' - the field containing the name of the unit load for a unit sanitary load. Note: not every one of these fields will necessarily be used. For example, if you are only importing pattern loads, you would only need to link the "Pattern (Label)" and "Base Flow" fields. Once completed, your window will look similar to this: Note that if you need to import a hydrograph load, the process is different and outside the scope of this TechNote. The table of flow vs. time needs to be imported first, using the hydrograph table type. The load would then need to be assigned to the manhole using the index in the sanitary or inflow collection table type. Click Next and choose to build the model. Check the "Messages" tab for any warnings and then close Modelbuilder. Open the Sanitary Load Control Center. The loads should have been imported correctly. Note that the loads/inflow that you import using Modelbuilder will be imported into the scenario that is active before opening Modelbuilder. This means that the loading/inflow data is imported into the "Sanitary Loading" or "Inflow" alternative assigned to that scenario. For a pattern based load, if the pattern is "fixed", you'll get a warning at the end of the Modelbuilder run that the Fixed load could not be found. This message can be ignored, but if you have a lot of fixed loads and you're doing a steady state analysis, you may want to consider importing them as Fixed inflows instead. This is a special type of load that falls under the "Inflow category". This involves only a single value, so you don't have to associate it with a pattern.

Forum Post: RE: Sanitary Load control Center
Hello, I did some testing with a sample model. I created a simple model with just a couple of manholes. I also created spreadsheet as specified in the TechNote with the unit load information. Below is a screenshot of the spreadsheet setup: Note that MH-1 is listed twice and that two different unit loads are being used (Industrial and Residential). The formatting of your spreadsheet will need to be similar, with each manhole and unit load in its own row. In your example, you have listings for Residential, visitors, and workers for MH-01. You will need to alter your spreadsheet so you have MH-01 listed in three rows, and the unit load each row being set to either Residential, visitors, or workers. The appropriate unit count will be included as well. Back to my sample model, I went through the ModelBuilder process as stated in the support solution for the issue. When I did this, the two different unit loads were correctly applied to MH-1, as seen in the screenshot below. The key is that you must have all unit loads in the spreadsheet to begin with. My suggestion of updating is not accurate, as this will overwrite the existing information. If it is all there to begin with though, all data should be included. I have updated the support solution to include the information above. Regarding the attributes "Load Definition (ID)," "Load Definition (Label)," "Unit Sanitary Load (ID)," and "Unit Sanitary Load (Label)", the definitions for these are given in the support solution. "Load Definition (Label)" is the field containing the type of sanitary load you are importing and "Unit Sanitary Load (Label)" is the field containing the name of the unit load for a unit sanitary load. As for the "ID" attributes, the ID is an internal number generated by the program. This is not required in the process and you should just use the label instead. Regarding the last item, if the Label you are using does not match up with any label in the model, a new manhole will be created. You will need to make sure that the labels in the spreadsheet match with the labels in the model. For instance, with the spreadsheet label is "MH-01" and the model label is "MH-1", a new manhole called MH-01 will be created at the default location in the model, which is typically at X:0.00 ft, Y:0.00 ft.

Wiki Page: Modeling Reference - Check Valves [TN]
Applies To Product(s): Bentley HAMMER Version(s): V8i Environment: N/A Area: Modeling Subarea: N/A Original Author: Jesse Dringoli, Bentley Technical Support Group Overview HAMMER provides several different ways to model a check valve, otherwise known as a “non-return” or “backflow preventer”. The following technote explains how each type of check valve works and when to use it. Pipe Check Valve The first and simplest way to model a check valve in HAMMER is to place it on a pipe element. This is done by simply selecting “true” for the “has check valve” property of the pipe. This would be done on the pipe where the check valve would be located. With this check valve approach, the following is assumed during the transient simulation: The check valve is located at the center point of the pipe The check valve closes instantly on first detection of reverse flow When using a check valve on a pipe, you will notice a symbol appear on the pipe: Pump Check Valve Another way to model a check valve is through the pump node element. If you’re modeling a Shut After Time Delay event, this is done by selecting “Check Valve” for the “Pump Valve Type”. If you’re modeling a Pump Startup or Variable Speed event, this is done by entering a zero for the “Time (For Valve To Operate)” field. This approach would be used if you have a check valve built into your pump, or if you’d like to assume the distance between the pump and downstream check valve is negligible. Similar to the pipe check valve, an instant closure is assumed, upon first detection of reverse flow. The pump node itself closes, preventing reverse flow. Check Valve Node The third way to model a check valve is by using the Check Valve node element. Simply place the check valve node in place of a junction, or even along the length of the pipe where the check valve exists (choose ‘yes’ when asked if you’d like to split the pipe). The check valve node approach should be used when: You’d like to see the check valve as a node, for visual or reporting purposes. You need to model a check valve that has a delayed closure instead of an instant closure. You need to model other advanced things, such as the pressure required to re-open the valve. The check valve node element is more flexible than the pump and pipe check valves, since it provides the following settings: Closing Time: The time to close the valve, from the fully open position, after reverse flow is sensed. This also establishes the linear rate of closure used if the valve is partially open when it starts to close. Set this to zero for instantaneous closure. Pressure Threshold –The pressure difference between the upstream and downstream side needed to reopen a closed check valve. If you select zero for this, the valve will reopen as soon as the upstream pressure exceeds the downstream pressure. Opening Time: The time to open the valve, from the fully closed position, after the specified valve opening pressure threshold is exceeded. This also establishes the linear rate of opening used if the valve is partially closed when it starts to open. Set this to zero for instantaneous opening Allow Disruption of Operation?: Denotes whether an operation (opening or closing) can be terminated prematurely due to a signal to reverse. False means that an opening or closing operation must complete once it starts (useful, for example, if the check valve is motorized and must fully close or open). True means that an opening or closing operation may be aborted at any time if the system conditions dictate. For example, if the check valve is half closed and the system pressures change (so that upstream pressure becomes higher than downstream pressure), then the valve will start to open again. Normally this field will be set to ‘True’. When using the check valve node element, you will see a user notification message for each change in the check valve position (starting to open, starting to close and interruptions) Introducing a delay in the closure of a check valve may prove to be more accurate, and sometimes more conservative. The reason is because in the case of an instantly closing check valve, the water column is essentially at rest at the time when it closes (zero flow). In contrast, if it takes some amount of time to close the check valve, momentum from the reverse flow is allowed to build up before the closure. Therefore the water column has some energy when the check valve closes, often resulting in more severe upsurge pressures. Consider the below graphs, which show the head and flow over time for an emergency pump shut down event, comparing instant closure (using either the pipe or pump check valve) to slow closure with a delay of 0.1 seconds and 0.5 seconds (using the check valve node). In the two slow closure cases, you can see that the peak HGL is higher than in the instant closure case. After 5 seconds, you can see from the flow graph that some reverse velocity has built up as the check valve closes, causing the increased pressure surge when the valve has fully closed. You can also observe that a closure delay of 0.5 seconds results in a higher pressure surge than a delay of 0.1 seconds, due to the increased time for reverse velocity to increase.

Also, after setting up the prototypes (and other standards), you can save the model to a Seed file. When starting a new project, you would then open from that Seed file. You can read a bit more about Seed Files in the help or by searching on Communities.

What is the install order for the files? Solution Most of the time you will only need to install two files. Those files are the main application installation file and the patch set file. The main application installation file is the larger file, likely a few hundred megabytes (MB). The patch set is the smaller file, likely a under 100 MB. You need to install the main application file first and then run the patch set executable. The other two files you may have downloaded are the "Prerequisites for Bentley Desktop" and "i-model Publishing Engine". You will not need these unless you plan to export your model to an "i-model" format, in order to share it with users who may not have access to the program, but may have a Bentley MicroStation, Bentley View, or similar programs that allow users to view i-models. More information on i-models can be found in the Help documentation. The "Prerequisites for Bentley Desktop Application" file is package that must be run before the installation of MicroStation any of the releases of the MicroStation V8i derivative products (Bentley View, ProjectWise Navigator, or MicroStation PowerDraft). It is merely an installation sequence of various Microsoft packages that must be in place before MicroStation or its derivative products will install and run correctly. The "i-model Publishing Engine" is the feature that allows a user to export a model in a Haestad program (like WaterGEMS or SewerGEMS) to the i-model format. Users who do not have the program but have access to Bentley MicroStation, Bentley View, or similar will still be able to view the model as well as element properties. If you plan to install all four of the installation files that you have downloaded then please use this order: 1) Prerequisites for Bentley Desktop 2) Application 3) i-model Publishing Engine 4) Application Patch Set See Also How to download WaterGEMS WaterCAD HAMMER SewerGEMS SewerCAD CivilStorm StormCAD PondPack FlowMaster CulvertMaster Cumulative patch set information and software update information

Forum Post: RE: Bently PondPack V8i Problem - Adding engineering library from ProjectWise
Certainly, I will try my best. For this example, I will be making a new XML file. I have created a PondPack model by opening PondPack V8i --> Create New Project --> and creating my Pre/Post Development scenarios. I then go to Components --> Engineering Libraries. I select storm event groups and click "Create new Library". This prompts me to create a name for the library and a place to put it. Since I am not able to save it into ProjectWise at this point, I temporarily save it to my desktop. (Note: I think this is where it is messing up. I think there should be an option here to be able to save a library directly to a folder within ProjectWise.) Next I go to Components --> Storm Data --> New Time-Depth button. I create my storm event by adding return event from dimensionless curve and input the appropriate data. After that is setup, I select the storm I created and I click the blue book button that represents the Engineering Library then I click "Export to Library..." To sync it with the Library I just created. So at this point, I have the Engineering Library and the storm associated with it all set up and working. I now want to put this Engineering Library onto ProjectWise. I simply copy and paste it from my desktop into the appropriate folder on ProjectWise. At this point, since I have my Engineering Library on ProjectWise, I delete the library that is on my desktop. I go back into my PondPack Model and go to Components --> Engineering Libraries and I remove the xml file that it was referencing off of my desktop. I then right click the Storm Event Groups and click ProjectWise add existing library. Here I navigate to the correct folder and select the XML that I had copied from my desktop into my ProjectWise folder. I click open to apply it to my model and I get the error "The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data." I hope that helps
