wake refinement
 

Hi all,
After a fustrating battle with Snappy to grow prism layers on my airfocorrect?ing i want to see if enGrid is the solution for me.
Before i get started, i would like to know if enGrid will be able to help me with my next problem (assuming layer generation will work): mesh refinement in the wake region.

My foil has a complex 3d shape so i was planing to extrude a surface behind the trailing edge and use it to refine the mesh localy.

Is this the right way to go?

Can this surface be ignored when i export the mesh to OpenFOAM?

I also read something about enGrid being able to produce an Hex mesh. Is this correct?

Thanks for your advice.
Stephane.
