Note that I looked at your attached StormNET model. Note that the current release of StormNET cannot have storm drain inlets that have two separate outlet (downstream) drain pipes. If you look at Inlet-34, you have links Con-31 and Con-23 defined as downstream pipes that route the flow captured at Inlet-34. Con-47 is defined as the roadway by-pass link.

The way to get around this is to add a computational nodal point (i.e., Junction) just downstream of Inlet-34 and have links Con-31 and Con-23 connect to this computational point. Then, have a short pipe or direct connection between Inlet-34 and the computational point. The invert and the top of the computational point can be the same as the pipes it is connecting to.

We have planned for a future version of StormNET to handle multiple downstream outlet drain pipes from inlets. For the mean time, however, you need to model it as I have described.

If you continue to face problems, please let me know.
