Wall boundry in MRF or Moving mesh

Hi,
I'm modeling a turbine ventilator which is turning in z direction. the free stream is in x direction. its a kind of turbine which you can consider like a savonius turbine with many blades. I sketched a cylinder around the turbine ventilator as an interior. I would like to know for MRF and Moving mesh which boundary I must assign for turbine blades. I mean if I use the MRF method the wall should be moving wall with relative velocity or absolute velocity or anything else. Generally which boundary condition must be used in my case. best regards, Amir. |

Moving wall with relative velocity of 0.

Dear Davy,
Is it applicable for both MRF and Moving mesh method? Regards, Amir. |

this condition applies to both cases and usually you have no need to specify again since the moving wall is adjacent to a moving zone (MRF)
