importing .stl file to Fluent
 

Hello,

I have .stl file which is a surface mesh. I want to import to Fluent 12.0, but there is no option to do that. Does anyone know how to work this out. I have ICEM software to use but am unable to make a closed volume out of the mesh.

Also I tried rhino to import .stl file but am unable to make a closed volume for CFD setup.

Any information will be of great help.
