A multi-region mesh was assigned - this analysis-type requires a single-region mesh


#1

hello,
My simulation run shows an error “A multi-region mesh was assigned - this analysis-type requires a single-region mesh.” As I am new to this simulation I don’t know what it means.
can you help me?

Hi @sickman: In your case (you have MRF zone around propeller) you need to prepare mesh for external CFD simulation. So called now ‘standard’ mesh (or TET based mesh) cannot be used. You should select Algorithm ‘Hex standard…’ or ‘Hex standard parametric…’.

Moreover, your geometry needs only the propeller and rotating zone. Boundary (BMB) can be defined while defining meshing params with SImScale.

thanks for the reply and suggestion.
