I am a novice when it comes to flow simulation. I have been trying for few hours to get my pump simulation with rotating region to work with no luck. I think I have set all the conditions and settings correctly, but just as I run the simulation I get an error "Mesh generation abnormally terminated - contact support". Geometry is ok, and I have checked all the other things that I can think off. Attached files below. Any help will be gladly appreciated.
