Hi, I've a solid geometry imported as a STEP file from ProE. I exported it to GAMBIT, then created a cylinder and enclosed the geometry inside it. I then subtracted the volume of the solid from that of the cylinder to get the flow domain within and around the solid. Then to mesh the flow field, I directly meshed the subtracted volume without meshing either the edges or the faces. Is this correct? I tried following the hierarchy of GAMBIT- i.e., mesg edges, then faces, and finally the volume. But there was always some error and the program crashed. So I meshed the volume directly. I want to know if this is OK or will it cause problems after taking it to FLUENT?

Thanks, Vidya

if you successfully checked for meshed volume using quality commands and see no voids, you're alrite,

I checked the mesh using the EXAMINE MESH command and it showed that the two indicators (which indicate the quality of the mesh) were at the middle, so does that mean that the mesh is 50% ok? The mesh looked coarse though. It was triangular and the type was Pave.

Is this ok?

Thanks, Vidya

NO, it just gives you the quality of your mesh in terms of the skew angle etc..., it means you have a mesh. A mesh is either existing and workable or its not, there;s nothing in between. A bad mesh could be workable as well. Read more on quality of mesh, its effects on the solution.
