[NXJournal - Python] Problem with FEM Mesh Generator

[NXJournal - Python] Problem with FEM Mesh Generator

[NXJournal - Python] Problem with FEM Mesh Generator


I'm relatively new to NXOpen (Journal).

So I'm trying to automate an FEM Simulation to understand the vibration characteristics of my part.
I have two problems.

1) I recorded the generation of the 3d tetrahedral mesh. Everything as usual.
But when I start the code, there is an Error with the mesh generator. The critical line of code is the following:

mesh3dTetBuilder1 = meshManager1.CreateMesh3dTetBuilder(NXOpen.CAE.Mesh3d.Null)

It gives the NXException: Internal Error. I can fix this error by clicking on "3D Tetrahedral" and opening the window for the mesh generator.
If the window is opened the error won't be raised. So it needs to be open somehow. Any idea how to automatically open it?

2) The window is opened and if I continue the journal, it raises a different error, because of this line of code:

added1 = mesh3dTetBuilder1.SelectionList.Add(cAEBody1)

This gives me an Internal Error: memory acces violation.
I read a lot about it here in the forum. My specs should be sufficient for the task:
Intel i5 3,1 Ghz, 4 core, RAM 8gb, windows10 enterprise
I think its probably because I don't have the administration rights in my company. Should a talk with the IT Department fix this issue?

You can read the full code in the attachment.

Greetings from germany and thanks in advance,
