"Unable to save model file. Please check file permissions."
Hi,
Firstly I've uploaded the .step file in HyperWorks and then I wanted to create a 3D mesh with tetramesh. I've used the options below.
After the mesh is created, if I try to save the model, the error message appears.

If I use a 1st order mesh (in element order section) it gives me no error. If I use the second order mesh, the message appears and I'm unable to continue the project.
Why does it happen?
Thank you.
