I have downloaded the testcases from git hub.
and when I am trying to import msh file to pyfrm , it shows the value error
How can I solve this error?
Can you confirm where the cavity_flow_d2.msh file came from?
Based on your error message, I think it is most likely that your mesh file is wrong in some way. Did you generate the mesh in gmsh or pointwise?
I have taken the case from Github repository.
That’s quite an old repo, so I would be wary using a mesh from there. The cavity flow case is quite straightforward, so it should be to hard for you to knock up a 2D mesh in gmsh or pointwise.
