Hi @Zaapex Your simulation’s mesh event log is showing two error warning which are as follows.
1)The tesselated surface is not closed. There could be a problem with the CAD geometry (such as self-intersections). Please inspect your geometry. Trying to proceed anyway.
2)The machine ran out of memory. Please choose a larger machine by increasing the number of computing cores or reduce the fineness of your mesh.
The second error can be resolved as suggested by @jousefm (thanks for the advice).
But as far as the first one error is concerned, i suggest you to check your CAD model , make sure that the CAD model is clean.
Here, see that geometry event log is also indicating the issue with CAD model.
Also upload the STEP CAD format of the model inspite of PRC. STEP CAD format is less likely to create meshing problem.
