• Water Level Spike in Surge Vessels

    Hi Bentley community, We are currently doing a detailed design for surge mitigation project and we are using HAMMER to simulate transient event. The model is extremely simple: Pumps Station -> Surge vessel #1 -> 2 km main-> Surge Vessel #2 -> 2 km…
  • Culvert Failure Analysis -- Which Program?

    I am looking to model a 72-inch CMP storm drain failure due to excessive thrust I suspect. I want to simulate the pipe failure, sink hole formation, the water surfacing, and the subsequent scouring. It's a bit of a tall order and will require substantial…
  • Solvers - General Question - SewerGEMS

    Using: SewerGEMS V8i, Series 3, 08.11.03.83 1. I used to model lift stations with wet well with a short fat gravity pipe between the wet well and pump. Under the GVF-Convex solver, this is not longer the case. I am curious to know what is the reasoning…
