I'm supposed to do Moving Reference Frame and Sliding Mesh Simulations of a Wind Turbine using a model that I got from my professor, see link.

When I imported them using DesignModeler the rotors were missing. Importing them with Discovery fixed that issue and even when I switched back to DesignModeler they were still there.

However, when I tried the meshing step, they disappeared again. At first, I thought that was due to geometry errors, but even after fixing those, the problem persists.

My professor thinks it could be due to conflicting element orientation, but I don't know how to see and change those. Is that possible, if so then how?

This is how the problem looks:

I tried meshing it with FluentMeshing instead of Mechanical, but then I get an error that it couldn't mesh one of the rotors.

What's a bit strange is that it seems to work in the file with the geometry errors if I keep the standard mesh size. The issue is that this is to large for some of the objects.

Any idea what's causing this and how I can fix it?

This seems to be a problem with the original input geometry. 
We are not permitted to access data files in this forum, so I am not able to determine the original source format. 
Perhaps try a different format type. Parasolid is preferred.

The original geometry is a .SLDPRT file which I imported as part of a .SLDASM file (SOLIDWORKS files). I also tried importing in Inventor and then importing the .iam file, however I was unsuccessful with that. I'm assuming it's due to Autodesk Inventor Professional 2026 not being compatible with Workbench 2025 R2 as I did launch CAD Configuration Manager as an administrator. Autodesk Fusion also didn't work for some reason. What program spits out Parasolid files, NX? Because I can't find that in the CAD Configuration Manager directly.

Parasolid is a geometry format usually with .x_t or .x_b extension.
Programs such as SolidWorks can export to Parasolid format, or neutral formats such as STEP or IGES.
