Unexpected Mesh Error


I’ve been trying to mesh a propeller to analyze its performance. I want to use a MRF to simulate the rotation of the propeller. For some reason the mesh keeps failing, but the error I get does not provide a lot of information. It only says: “An unexpected error happened during mesh generation”. When I check the mesh log, it looks as if the mesh was successfully generated.

Any advice?

This is the link to the project:



Could you try replacing the word “Rotor” for “Zone” here, in the cell zone definition?

This should allow the mesh to finish.

Hi Ricardo!

It worked! Thanks. It was actually just a simple mistake.

Thanks again.
