• WaterCAD UDF Flushing simulations velocity

    When running WaterCAD UDF Flushing simulations, when I isolate out a pipe section in the network, why do other pipes in the network still have flow even though there is theoretically no source?

  • Backflow in tank, watergems

    I am generating a model, which all tanks are at same elevation, so when 1 tank gets empty, other tanks try to fill it, insted of pums. right now i have solved using PRV in outflow pipe and capping pressure just bellow tank elevation. is there any…
  • How can I create a catalog pipe class size in watergems, such as in SewerCAD or SeweGEMS??

    I would like to create a table with the data of internal diameter for each nominal diameter pipe that I have, so in properties I can select each nominal diameter and automatically update the internal diameter according to the created table. In SerweGEMS…
  • Customers meters association in the juctions but considering the closest pipe

    In old WaterGEMS V8i It could associate Customers Meters in the juctions but first checking the closest pipe. I mean, the software get the closest pipe then considering the distance of the start and stop node it get associated with the closest node. In…

  • Flushing Analysis

    Hello Bentley Community, I am performing flushing analysis for our water model network with 1515 active hydrants. I have the following questions 1. Is there a way to run the flushing analysis that would indicate the order or sequence of hydrants to…
  • Low pressure and high velocity

    Hi, I am a doing modelling for improvement of the existing system. Many location velocities are high and pressure is low. Even I tried to increase the pump capacity the pressure is not increased. Please check the model in the below following link…
  • No Flow in tank Top inlet fill

    Hi, I have another issue in the model, If you check the T-1 inlet it was connected as a top inlet. When I run the simulation for avg daily demand I don't have any issue. However, when I run the same model with Max daily demand scenario (Peak factor…

    Hello, how could I model area change in bentley hammer ? Is there any method rather than splitting pipe? does pipe splitting do better simulation for Wave Reflection and Transmission at an expansion and a contraction?
