I think it's research. The solver is not any of the ANSYS products. The solver is for LES and I really want to avoid any kind of non-hex cells. With regards to the approach you mentioned, is there any specific tutorial or video you can please point me to ? Also, can ANSYS meshing be automated through a Python script ? I unfortunately cannot visualize large cells. Ideally, I would want to generate a 2D mesh, sweep it radially and then generate the centre OGrid-style mesh. I can then write a shell script to take care of post-ANSYS operations.
Thank you for reading.
