Good morning,

in a student's project I'm working on a topology optimization using Functional Generative Design in 3DEXPERIENCE R2021x, but I always get stuck during "Preparing for simulation" of the setup validation showing the attached message in the diagnostic viewer.

I'm pretty sure, that there is no obvious mistake in my setup. I tried a lot, but wasn't able to fix this problem.

Has someone an idea or a hint how to fix this? Thanks in advance.
