Hi.
I was trying to export mesh to Nastran without success. It seems that *.dat files are not readable by Nastran and when I tried to export using meshio every time I’m getting the same error. I’m not a programmer and I don’t know what to do with it. Could you help me please?

Hi,
open the file _nastran.py located in the path shown in the error message. Line 413, set precision to 9 instead of 11.

Hi. This solves one of the issues. List is shorter now, error still remains.
I tried some other formats. The mesh is being exported without any issues. But the only format I need is Nastran.
Hi,
edges with 3 nodes were not managed. Please find an updated _nastran.py that:
- add BEAM3 element
- skip not managed elements types (instead of raising an error)
- decrease precision only if needed (instead of harcoding it to 9 as I answered before).
If you don’t need BEAM3 elements you can also remove all edges of your mesh by:
- creating a group of edges and tick “select all”
- right-click on the group> “Delete groups with contents”

Thank you, Christophe, your changes seem to solve the problem. I need to confirm that with a friend of mine. I’ll let you know if he had any issues importing the mesh.
There were no issues importing mesh. Thank you again.
