Hi! all

Iam currently doing a case where i want to simulate a stirred tank reactor. The tank reactor is quadratic in shape and have an impeller in the center. Iam using Multiple reference frame (MRF) for the rotational region. However i have some difficulties with the meshing i would want a hexahedral mesh in the tank and a tetrahedral mesh in the cylindrically shaped rotational region. Which meshing method is most suitable for this? and how can it be done? iam kinda stuck on this part and i would really appreciate some help. I will attach some images of the geometry for visualization.

Thanks in advance
