Hi,
We've a small subdivision area that happens to receive flow from other external areas. Originally the model was built in StormCAD as those external areas were routed somewhere else and didn't interact with the new subdivision but later on got to have the flow routed through our area after the location of a retention pond was changed during land use planning.
The model was originally built and run in StormCAD as it met the requirements but then after the external catchments identified we opted for hydrodynamic in Civil Storm. To do so, we first added the external catchments to the StormCAD model and defined their parameters and ran the model to get some initial pipe sizing. We then opened the model in Civil Storm and defined the hyetograph, CN, and unit hydro-graph..etc and set up analysis mode using explicit engine.
We ran validation and it runs fine, but ran the model and it shows unspecified error messages. We're running CivilStorm 10.01.00.70 on Autodesk Civil 3D 2017.
when we open the model from the standalone interface it just crashes.
I tried exporting the model as a sub-model and importing it into a new empty model file and the model did complete the run.
What is happening?
