Hi, while meshing my volume in gambit, i am getting an error message saying " logical cube for meshing was not able to found" and meshing it.. but, when i export that to fluent one of the interface in that volume is skipping, i tried mesh at different sizes of grid the same problem persisted.. kindly help.

thank you

a non logical cube for meshing in gambit is for example a face that is made up of edges that do not meet. So take a small circle inside a large circle on the same plane. Then subtract the smaller from the larger to be left with an annular face. This is a face that cannot be constructed from its 2 edges directly in gambit and is a non logical cube. Workaround is to break the face up into smaller faces each having edges to do close.
