Hi,

I am looking to use OpenFOAM to model an unbaffled stirred tank reactor agitated by a magnetic rod stirrer (located as base of reactor) as shown in image. The system will consist of air-water, where the interface between the two phases will deform inducing a vortex. I've simulated this case before in ANSYS FLUENT.

As the case is quite complex (including rotating stirrer, multi-phase flow, etc) I need advice on how to go about setting up this case (i.e., a workflow).

I know I want to use a single reference frame (SRF) model for the rotation, and Volume of Fluid (VOF) to track free surface deformation.

Also, what advice would you give in regards to meshing tool. I know OpenFOAM has an inbuilt mesher (snappy hexmesh) which can produce hexes. How easy will it be to implement hexes for my geometry as previously I've used a tet mesh using ANSYS Mesher?
