Hi CFD-Online Community,
I used Star-CCM + for 13 months and now have to switch to Ansys for professional reasons. What can you recommend for geometry preparation?
Did Ansys has something like the Surface Wrapper from Star-CCM+ ?
Are there possibilities to use something like the "Surface Repair"?
I was currently recommended ICEM CFD. Thank you very much for all the tips and advice. I hope there are some who master both programs.

The go to geometry preparation ANSYS application is SpaceClaim. You might have access to the legacy DesignModeler application, but SpaceClaim should be your preferred option. Recently SpaceClaim has incorporated mesh generation capabilities, which by the look of them is going to be the replacement for ICEM CFD (although I have not seen that confirmed).

ICEM CFD is good for multi-block structured meshes and large tetra/prism meshes but the GUI is old and maybe less user-friendly for a new user. But for geometry preparation I would go to SpaceClaim.

Use Spaceclaim. This is best for geometry clean up.
Then the mesher.........what solver wil you be using?
If Fluent, then start with Fluent Meshing. This can generate tets, prisms, hex and polyhedra.
If CFX, then the workbench mesher is the fastest for tets, prisms and hex. CFX can't handle polyhedra or cut cell meshes since it is a node based solver. This makes that a tet mesh in CFX is equal to a polyhedra solution in Star-CCM+ or Fluent.

I only use ICEM as last resort if I need a perfect structured Hex mesh or if I have very sloppy CAD. But it has a long learning curve. Also ICEM is a dead end. No enhancements anymore.
