Hey guys,


i get the following error message when starting my new project:

Can anyone help me with this problem?

Hello Chris,
It's a good practice to run your problem in debug mode which locates your error exactly. This helps you in future to understand the code easily. Check this link,

Good luck

Thank you very much, this helped a lot!

So the solution that i found was to run the bash command renumberMesh -overwrite after creating the mesh in pointwise. Maybe this helps somebody else.
