Can we run both sewer and storm model in sewer gems if yes which solver should I use because our client requirement is a combined sewer
Hello Naveen,
To model combined storm-sewer system in SewerGEMS, we recommend using dynamic solvers of SewerGEMS e.g. Implicit solver.
Please read more about solver selection in SewerGEMS, using link mentioned below.
Differences between solvers: GVF-Convex vs. GVF-Rational vs. Implicit vs. Explicit (SWMM)
Please note that SewerCAD Convex solver is better designed to handle pumping. It can run steady state calculation(with peak factor simulation) as well as extended period simulations. If you're looking for a fully dynamic solution that considers all overflows from the system with less pumping or less complicated pumping controls you should consider the Implicit solver in SewerGEMS or the SWMM solver.
