I am trying to solve a backward-facing step problem using SimNet. I have created a mesh using SimNet only and gave proper BC. But in this case, my solution is not moving at all. It is not improving after running a long time and loss is also not decreasing.
Also, I am not understanding, how to create validation data for such problem as I don’t have an OpenFOAM case file for it.
I am attaching my code here.back_step.py (5.5 KB)
