I used four edges in a wedge shape to refine a mesh around a cylinder (2-D), the problem is Fluent treats them as a wall, even when I tell Gambit to leave them as unspecified boundaries. How can I "hide" the geometry in Gambit? I can't delete them since the mesh is dependent on them.

You may delete the zones which you don't require from fluent's surface>zone>manage(surface) panel.

Hi Manoj,

I just found two problems with my mesh, inside the wedge the fluid was unspecified, and I had duplicate edges that made up the wedge. I fixed those problems and it worked! Thanks for your suggestion, I did not know about the zone options in Fluent.
