James, No, there is not. StormCAD was not designed to model overflows because it uses a steady state peak flow solver. This wiki technote will explain what happens to overflow at a manhole or inlet in StormCAD: communities.bentley.com/.../11166.why-is-the-hgl-reset-to-rim-elevation-for-flooded-structures There should be a user notification when you run into this situation that explains that all flows that leave the system are accounted for at the network outfall. If you'd like to account for overflows you'll need to use one of the dynamic modeling software applications that we offer like SewerGEMS or CivilStorm. The good thing about these two applications is they both include the StormCAD GVF Rational solver and the EPA SWMM solver, as well as the implicit solver. Both the SWMM solver and the implicit solver are dynamic and will account for flooding at the structures. SewerGEMS also offers the SewerCAD GVF Convex solver along with the other solvers. These wiki that explain the differences an similarities between the applications might be of interest to you. communities.bentley.com/.../12768.difference-between-civilstorm-and-sewergems communities.bentley.com/.../21485.what-are-the-differences-between-stormcad-and-civilstorm-when-should-i-use-stormcad-instead-of-civilstorm communities.bentley.com/.../11852.sewercad-gvf-convex-solver-vs-sewergems-implicit-and-explicit-dynamic-solvers You may also see a discontinuity at steep pipes and be curious about that, especially if you have a large system, so I've included this wiki link below to answer that question for you preemptively. It might also help you understand more how StormCAD works. communities.bentley.com/.../10149.hydraulic-grade-discontinuity-at-steep-pipes-or-across-nodes-frontwater-analysis I think these wiki links should answer your questions, but if you have any more please let us know.
