How to set inflation layer?
 

Hello everyone,

While doing my final project which consists on simulating the flow around a parabolic dish anttena I "found" a problem with the meshing.

I did the geometry with inventor and I exported to ansys, then I create an enclosure, but I don't know how to create the appropiate mesh.

My problems are:

1-The way I did the geometry is the good way?
2-Can I create inflation layer only in the zone I want and how?
3-Is posible not to mesh the interior part of the antenna?

Thank you very much for your help.
