I ahve a super sonic 3d problem but i can't reach convergence below 10e-3 i checked the mesh in fluent and noticed that fluent ruined hexa mesh in some areas i have made the mesh in gambit almost all of it hex . My problem is a missile with canar and tail fins here is a picture in the x plane in the canar area please can any one tell me is that normal?

You obviously have dynamic meshing options on, otherwise Fluent does not do any meshing. Fluent only adapts those cells that you've marked, so you might want to reconsider your criteria for marking cells.
