Meshing stirred tank
 

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

Hi

Which mesh generation software you are using for your case?

Hi!

Iam using workbench fluent meshing application

Kind Regards Shaafi

Tgrid, ansys meshing or Gambit?

Sorry about that i meant the ansys meshing :)

did you take a look on similar cases at ansys meshing and geometry forum?

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
