I am trying to run a simulation in CFX to analyse flow through a DAWT and so far I have been running into a few problems.

The method I have been using is to model the geometry in solidworks and exporting as a parasolid text file which i import into the ansys geometry modeller. I then create a cylindrical enclosure around the geometry and subtract from the enclosure using a boolean.

Ideally I would like to have a hex dominant mesh on my geometry but all I can get is a patch independent tetra mesh and when I try to run the solver on this mesh it causes a failure.

If anyone could give me some ideas for getting a better mesh or a reason why the solver is crashing I would very much appreciate it.
