Forum Post: Hammer Model -errors with related to the use of D2As
Hi, I'm modelling pump trip scenario in a water distribution network. The network in reality will be configured of main lines and zones. From main lines, zone control valves will control the flow to each zone. There are 65 zones. I modelled the zone control valve as a D2A, where the D2A will only allow discharge if the pressure reaches higher than 12.74 m. My intention is to stop the flow to customers when the pressure in the network drops, and therefore in pump trip scenario the network should remain pressurized. I also added a surge vessel d/s the pump station to absorbed high/low pressures. For the pump trip scenario, the initial conditions runs fine with approx. 1283 L/s flow rate. All D2As have discharge flow. The issue I'm having is that when I run the pump trip scenario, the simulation is never completed due to error messages. It looks like the model is unstable. I'm unable to identify the source of instability. I changed the parameters of the surge vessel, added points to the D2A curves, changed the time step but no luck. However, I've noticed that the simulation progress improves when changing the size of surge vessel, although I don't know why this is relevant. I appreciate if you can look at this model and provide guidance to what may be the cause(s). I will upload the model. The scenario I'm looking at is the active scenario. Regards, Fadi Sirrieh

Forum Post: RE: FLOW GOING OUT OF A TANK EXCEEDS THE LOGICAL FLOW
Carlos, The outflow from your tank is equal to the sum of the downstream demands, because the downstream demands have no other source of water. Your reservoir and pump are not connected to any of the demands downstream of the tank. If you look at the Calculation Summary that appears after computing the model, you will see that the "flow demanded" is 1180 L/s There are just a few demand nodes between the pump/reservoir and the tank but the majority (988 L/s) is downstream of the tank. In a steady state simulation, the outflow from the tank is independent from the volume of water in the tank. In reality, maybe your tank would drain out very quickly with an outflow of 988 L/s, but when you're looking at a steady state simulation, tank levels do not change. In that "snapshot" of time, the flow is based on balancing energy and satisfying demands in the model. If you run an EPS, then based on the volume of water that would leave the tank in the first time step increment, WaterCAD would adjust the tank level accordingly. Is it possible that a mistake was made when entering the demands, and the demands are much higher than they should be? If you go to Tools > Demand Control Center, you can sort on Base Demand to see where the largest demands are. There are several nodes with 30 + L/s

Forum Post: RE: FLOW GOING OUT OF A TANK EXCEEDS THE LOGICAL FLOW
HI JESSE GOOD MORNING. THE DEMAND AT THE NODES ARE THE SUM OF THE DOWNSTREAM NODES (OR APPORTING NODES TO A SINGLE ONE) STARTING FROM THE FURTHES TO THE CLOSEST TO THE TANK, THATS WHY THE NODE DOWNFLOW FROM THE TANK (J-430) IS 38.31 LPS. IN WATERCAD, SHOULD I INPUT AT THE NODE ONLY THE DEMAND REQUIRED BY THE LENGTH OF THE PIPE? MAYBE THAT IS MY MISTAKE AND THAT IS WHY THE FLOW DOWNSTREM OF THE TANK IS SO HIGH. ALSO I WANT A SUPPLY LINE FROM THE PUMP (WHERE THERE IS A WELL AND I AM ASSUMING IT AS A RESERVOIR) TO SUPPLY WATER TO THE TANK (T-2) AND FROM THAT TANK I WANT GRAVITY FLOW SUPPLY TO THE NETWORK. IS THIS IS WHAT I SHOULDED DONE SINCE THE BEGINING?

Forum Post: RE: FLOW GOING OUT OF A TANK EXCEEDS THE LOGICAL FLOW
Carlos, A demand at a node represents an individual outflow at that point, which the system needs to satisfy. For example if the average demand at a particular customer is 1 LPS, you would put 1 LPS as the base demand (a pattern can then be applied for EPS) and the hydraulics will be calculated such that 1 LPS leaves the system at that point. It may help to take a look at the pipe flow results to see how flow is routed to satisfy the demands. So, if the total demand downstream of the tank is 38.31 LPS, that should be distributed among all the nodes accordingly. For example a quick (but not very accurate) way to do this would be to divide by the number of nodes in the model and apply that to each node. You may want to take a look at some of the resources available in the below article: http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/11933.learning-resource-guide-for-new-users-of-bentley-watergems-watercad

Wiki Page: Distributing a lump sum demand over a large area
Applies To Product(s): Bentley WaterCAD, WaterGEMS Version(s): 08.11.xx.xx Environment: N/A Area: Layout and Data Input Subarea: Original Author: Jesse Dringoli, Bentley Systems, Inc. Problem How can you distribute a lump sum demand over a large area? Problem # 54617 Solution To distribute this demand over the model, one approach would be to use the Loadbuilder tool. Loadbuilder has several different methods of distributing demand information over the nodes in your model, based on spatial information. For example you could use the Proportional Distribution by area method. With this method, you could first generate a Thiessen polygon (using the Thiessen Polygon tool) to create polygon areas representing each junction in the model (service areas). Loadbuilder would then overlay the lump sum demand polygon shapefile that you have with the service areas and distribute the demand to each node based on the overlapping areas. You can read more about Loadbuilder in the help documentation. Alternatively, if you don't have spatial information (polygon(s)) for this demand and just know the total demand amount, you can divide it by the number of nodes in the model to find the demand per node, then use the "Initialize demands for all elements" option in the Demand Control Center (located under the Tools menu). This would create a single demand entry for every element, with the same demand amount. This would be the least accurate way to distribute the demand.

Forum Post: RE: Hammer Model -errors with related to the use of D2As
Hello Fadi, There are a couple of items that may need to be addressed in the model. First, you have a rating curve for each of the D2A elements. In those rating curves, at zero flow you have a pressure head of -10 meters. This is right at the vapor pressure and will likely need to be adjusted. You mention in your post that you want zero flow at 15.74 meters. You will likely want to have the pressure head value in the rating curve set to the appropriate value, with this value being the benchmark. In addition, the hydropneumatic tank in the model is really large (500 m^3). This large of a tank will actually impact the transient results quite a bit. Be sure that you have the correct units and size for the tank in the model to assure that the results are accurate. Also, you are doing a pump shut down using the Variable Speed/Torque setting. You might want to consider using the Shut Down after Time Delay setting instead. You can find information on the differences between these at the following link: http://communities.bentley.com/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/9076.pump-shut-down-speed-vs-torque-and-pump-start-up The first two items above might help best with the issue you are seeing. Please let us know if you have any additional questions. Regards, Scott

Forum Post: RE: Hammer Model -errors with related to the use of D2As
Scott, Thank you for the quick response. The surge vessel volume should be affecting the results of the model, but it should not cause errors. In any case, I now deleted the surge vessel but still get the error. I also changed the pump setup to shutdown after time delay and that also didn't eliminate the error. For the D2A, I originally started the profile with 12.74m (not 15.74) and 0 flow rate. I got the error as well. It's when I decided to add (-10m. 0 L/s) to try ensure that the model finds a value for the flow rate when the pressure drop. This didn't help as well. Is seems that the large quantity of D2As are causing the model's instability. I will replace those with other elements such as PRVs and see if this works.

Wiki Page: Performing clash detection of storm/sewer/water lines using Bentley Products.
Applies To Product(s): Bentley SewerCAD, Bentley SewerGEMS, Bentley WaterCAD, Bentley WaterGEMS, Bentley CivilStorm Version(s): 08.11.XX.XX Environment: N\A Area: Modeling Subarea: N\A Original Author: Sushma Choure, Bentley Technical Support Group Problem: Is it possible to perform the clash detection between storm/sewer/water models using Haestad Products? Solution: To perform the clash detection between the storm/sewer/water models you need to have Bentley Navigator or Subsurface Utility Engineering. It’s not possible to do that using Haestad products. Navigator is used to perform the clash detection but you cannot edit the models there. Whereas Subsurface Utility Engineering can perform the clash detection as well as you can make the changes in model there itself. Below are the options available to perform the clash detection. Option 1: Using Bentley Navigator for clash detection Export the i-models of E.g. storm & sewer models from StormCAD/SewerCAD/SewerGEMS. Import i-model into Bentley Navigator, perform the clash detection. Please note that i-models are not editable, so you can’t make changes in Navigator. Make the changes in models separately as observed in the clashes. Here is the support solution which explains how to perform clash detection in Bentley Navigator. http://communities.bentley.com/products/projectwise/project_review/w/wiki/8823.clash-detection-in-bentley-navigator Option 2 : Using Bentley Subsurface Utility Engineering for clash detection & editing. Export the shapefiles using Bentley SewerCAD/StormCAD/CivilStorm/SewerGEMS/WaterCAD/WaterGEMS for each element separately using Flex table. 2. Import the models (shapefile) into SUE (Subsurface Utility Engineering), using Modelbuilder. 3. Run the clash detection tool. 4. Adjust the element positions and elevations in SUE, if clashes are there. 5. Then use the Modelbuilder to sync out the data. 6. Build the model again in Haestad products using Modelbuilder. Here is the support solution which explains how to perform clash detection using Subsurface Utility Engineering. http://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/17691.video-clash-detection Also See : http://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/12600.subsurface-utility-engineering-sue-video-clips-technotes-faqs

Problem In plain MicroStation, when opening or referencing a DGN file that was part of a Hydraulics and Hydrology product (such as a StormCAD for MicroStation model), the color coding and annotation does not show up (it either does not appear, or color coding/annotations that were unchecked in element symbology show up) How can I ensure that the color coding and annotation that I see in the Microstation integrated mode of my Hydraulics and Hydrology product shows up in the same way when opened or referenced in plain MicroStation or a Bentley PowerPlatform product? Problem ID#: 92117 Solution This has been addressed in version 08.11.04.50 and above. In this version, go to the When working in the MicroStation integrated mode, the symbology is a "transient" element and does not save with the DGN file as changes are made, unless you explicitly tell it to. To do this, click the Hydraulics and Hydrology product menu (such as WaterGEMS), then click Project > Save Symbology to Drawing. Then, click File > Save. Now when the dgn file is opened in plain MicroStation, annotations and color coding that were unchecked should not appears. If you have a version of WaterGEMS, WaterCAD or HAMMER below 08.11.04.50, there was a known issue with disabled symbology still showing up in the DGN (items that were unchecked in element symbology). This has been addressed in version 08.11.04.50 and in other Hydraulics and Hydrology products release after May, 2013. Also, currently inactive node elements that were set to disappear in WaterGEMS/WaterCAD/HAMMER (by unchecking "display inactive topology in the Tools > Options menu) will still appears in a gray color (by default.) You can use these steps to manually remove them in plain MicroStation: 1. Start the select tool 2. Show tool settings details 3. Go to the Color tab and select the "Inactive Color" (typically gray) 4. Delete the selected elements

Forum Post: RE: Hammer Model -errors with related to the use of D2As
Hello Fadi, The D2As are indeed likely the cause of the problem. If you set up a small test model, you will see instability occur if the pressure at a rating curve-based D2A drops below the point on the rating curve corresponding to zero flow. The calculation failures you're encountering typically occur when the severity of model instability goes beyond a certain threshold, which is why it sometimes appears as if it is occurring at a random location. It agree that it may be best to consider another approach. One thing worth mentioning is that demands in HAMMER are always assumed to be pressure dependent during the transient simulation. Meaning, if you place a demand on a junction, it will satisfy that full demand during the initial condition, but as the pressure changes during the transient simulation, the outflow will change accordingly. If the pressure at the demand node drops to zero, the outflow will drop to zero. This may not be quite the same relationship that you would get if you have a valve that closes off demands as pressure drops, but it might be worth considering. You could set the demand node's elevation equal to the hydraulic grade corresponding to the desired pressure that shuts the valve. Another factor worth considering is the valve reaction time. If there is a valve in the system that closes dynamically, it may not be able to react and close within the small timescale that transients occur (a matter of seconds). A conservative assumption may need to be made for the boundary element representing such situations.

Wiki Page: Is it possible to have a pump curve in the pump definitions use linear interpolation (go from point to point) instead of follow a curve?
Applies To Product(s): Bentley WaterGEMS, Bentley WaterCAD, Bentley SewerCAD, Bentley SewerGEMS Version(s): 08.11.xx.xx Environment: N/A Area: Modeling Subarea: Original Author: Scott Kampa, Bentley Technical Support Group Problem Is it possible to have a pump curve in the pump definitions use linear interpolation (go from point to point) instead of follow a curve? Solution By default, the pump curves for WaterGEMS, WaterCAD, SewerCAD, and SewerGEMS follow a quadratic interpolation, giving the pump curve a smooth shape, as shown in the screnshot below. At times, a user might want a multipoint pump curve to follow a linear interpolation. This could be because the values in the pump curve may work better with a linear interpolation. For instance, there may be a large different in flow for a small change in head. A user may also have pump data from a manufacturer that follows a linear interpolated pump curve and want the data in the model to match exactly. In such cases, there is a setting in the calculation options where a user can set a multipoint pump curve to use linear interpolation. To use this, open the calculation option properties by going to Analysis > Calculation Options, then double-clicking the active calculation option. In WaterGEMS and WaterCAD, find the section called Hydraulics and change the setting for the attribute Use Linear Interpolation for Multipoint Pump Curves to "True". In SewerCAD, the same attribute can be found in the section called Pressure Hydraulics. Note: This only works for multipoint curves and not for three-point or one-point curves. If the user is using SewerGEMS, quadratic interpolation is also used as a default, and there is no direct way to change this. However, for SewerGEMS SELECTseries 3 and later, there is an indirect way to use linear interpolation for pumps. To do this, first change the Active Numerical Solver in the calculation options from "Implicit" or "Explicit" to "GVF-Convex (SewerCAD)". The SewerCAD calculation option properties will then be available, including the attribute Use Linear Interpolation for Multipoint Pump Curves. Change the setting of this property to "True", then change the Active Numerical Solver back to "Implicit" or "Explicit". The multipoint pump curve will not follow linear interpolation. With linear interpolation set, the pump curve will look like the screenshot below:
