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
Regards Shaafi

Hi

Which mesh generation software you are using for your case?

yes i did i made the ansys tutorial on stirred tank but the geometry in the tutorial was for a cylindrical shaped tank and i tried to apply the same meshing method(Sweep meshing) by decomposing my geometry with slicing approach so the geometry could more easily be swept but unfortionally it didnt work, and i have no clue how to go on from this point
