Hello,
I am currently working on a 2D only model with HEC-RAS 5.0.5 with two 2D flow areas that are connected by a bridge modelled as multi culvert weir as presented on this blog.
So far the model is running fine, but I want to increase the model resolution to decrease the simulation time. At this I keep on getting a mesh generation error in RAS Mapper for at least one of the 2D flow areas when I change the overall grid size or enforce a refinement region. The error says: “Failed to load. Start editing to recompute mesh.” Afterwards the mesh is displayed without the cellfaces and the layer information says 0 cells with 0 cell points.
When I open the geometry editor, everything looks fine and I can even run simulations.
Now my question: Is there a possibility to avoid this error in RAS Mapper?
Best regards
Paul
