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.
