I am using adaptive timestepping. For some reason, after finishing the first scenario, the SimCFD is stuck on "Surface meshing... 193/241"
This doesn't happen with a simple pipe geometry. So it is not a generic issue.
How to tackle this?
I'd check face no. 193. This may not fit herre, but sometimes a visible sketch from the original Inventor geometry can cause surface meshing issues. If you go to outline view the sketch should be visible in CFD. Hide it in Inventor...
