      Hi,


      I have solved my problems with meshing and I have obtained the mesh of a periodic sector of the fluid that passes through the impeller with quite good quality



       


      My question is, what simulation method could I use? Sliding mesh (SD) or rotating reference frame (MRF)? And, would it be possible to combine it with a periodic repetition of my sector? Since otherwise it would exceed the limits of the educational license in terms of bodies and parts





       


      Regards,


      Fran

      I advise you to go with sliding mesh method.

      But is not a transient problem, I need to analyze different points at different flow to obtain the characteristic curve of the pump, I supose in a static way, or I'm wrong? And sliding mesh method is for transient problems, is not it?
