I am currently designing a basin in Pondmaker. Everything goes smoothly until I run my outlet design. When I do, the program estimates my storm elevations at a very low depth as seen in the first...

Scott, Thank you for your rely. We also found that the head of the pump was too high and that was causing the pump to push a lot of water. We'll change the calculation setting. Should I change this for...

Hello Yoko, If the pump flow is too high and/or if you are getting a "Network Unbalanced" you should change the calculation options. If the results are fine, you can leave it as is. Regards, Scott

Hello, In order to look into this, we will need to see a copy of the model files. There are two options for sharing your model files on BE Communities. If you would like the files to be visible to...

Hello Tim, This is likely related to some user notifications that you are getting when you compute the predevelopment cases. If you compute the 1-yr predevelopment scenario, you see that you have user...

Hello Yoko, It looks like you added another pump and FCV to the model (pump Pump-WTP 2 and valve FCV-UF to Tank 2). Did you make other changes as well? Adjusting the calculation options on the model...

Scott, All other changes are explained above. But, I guess re-modifying the older model that works is a better option. I have it with me, so you don't have to send it. Thank you so so much! Have a...

We are evaluating transient pressures for a single feedermain. The feedermain has a single tie to the system and connects to a downstream reservoir. However there are a few ties from the pump station...

Hello Hamid, I'm not familiar with the guideline you mentioned but I'm confident you'll be able to use SewerGEMS to model this system. 1) When you mention a flow of 0.2 cms, is that a constant flow out...

For a transient analysis, you'll generally want to model things as closely to the real system as possible. Bentley HAMMER tends to be more sensitive to modeling artifacts (things placed to "force"...
