Hello
I am trying to run a hydraulic model with explicit calculation solver
However, the model does not run because of the following error
"culvert inlet coefficient assigned to this conduit has a swwm culvert code which only applies to culvert…
Hello,
My drainage network simulated in Sewergems Explicit solver is consist with Ponds and POS. I'm getting not converging %, more than 5%. It gives unstable flow results. When I check the report summary, it shows higher continuity error in POS. Is…
Hello,
I'm simulating a storm network in sewergems platform. My network is connecting with a pond and the variation of HGL of the pond and the U/S node of the incoming channel is shown below.
I'm using explicit solver, with 6 sec routing time step…
Hello,
I am simulating a stormwater network (in sewergems) where I have channels, conduits, manholes, Ponds (3 nos), POS, Pumps. I can not simulate this in Implicit solver (as it takes hours and giving unstable results).
When I simulate in Explicit…
Hello,
I'm simulating a drainage network in SewerGEMS. The network consist with open channels, closed conduits, pond, pump, POS(no control structure).
when I simulate the model in Explicit and implicit solvers, I'm getting two different profiles as…
Hello,
I'm simulating a stormwater network where I have a pond. in the pond outlet channel I need to introduce a stop control structure and assign a orifice gate where I can open/close it with SWWM control set
using pond water level. My issue is …
Hello,
I'm simulating my model in explicit solver and I have set the SWMM output increment to 0.1 hr. Then when I go for profile simulation, always my profile start with 0.1 hr. Is it possible to change it to Zero?

Using SewerGEMS Connect Edition 10.02.04.53
For manholes, I am wondering how the software calculates the area/volume of water that is stored over the rim elevation corresponding to the surcharge depth.
For example, below is a manhole that has…
Hello,
I'm simulating a stormwater model in sewergems platform. the network is simulating as open channel flow. further, network is bit complex with several tributaries with several sections (unlined trapezoidal, RCU rectangular drains, box culvert…
SewerGEMS: Why I have zero overflow volume (Hydraulic Reviewer manhole table) in manholes that show "True" in the "Is ever overflowing" field? I'm using the explicit SWMM solver and I don't have bolted covers. Thank you very much.
Hello, I have a SewerGEMS model set up to review 2, 10, 100, and 2500 year storm scenario's. For this model, the explicit solver achieved much better convergence and continuity error results for the 2, 10, and 100 year storms. However, I am seeing very…
Can someone explain to me what the "Time Step Critical Elements" are when running a SewerGEMS Model with the explicit solver? After a model run when looking through the summary report, there is a section titled "Time Step Critical Elements". My model…
I cannot for the life of me get this warning to disappear from my model. If someone could take a look at the node that is causing an error that would be great. The model contains a double barrel arch CMP pipe as an outlet structure for a pond. The pond…
hi guys hope you're doing fine
am just curious about : why there is an explicit and implicit solver?
isn't the implicit is the best one what ever ?
why modified rational method wont run on explicit ? and work on implicit
and thank you
coardially…
Daniel,
We have a wiki article that explains the difference between the StormCAD solver (GVF Rational engine) and the CivilStorm solver (Implicit or SWMM dynamic engine) that will help explain when to use each solver for the results that you're looking…
