Warning in Fluent meshing: The regions may not be computed correctly

      I got a lot of warning messages during my Fluent meshing session:

      Warning:

      The regions may not be computed correctly.

      Found overlapping faces sharing edge bn1134311-bn1134306...

      I am wondering why I am getting these warnings, whether it indicates errors in my CAD geometry, and what I should do about these warnings.

      Thanks!

      It can mean you have a folded surface, but it's also possible the surface mesh is chewing up the geometry. Some images of what you're trying to mesh will help. Otherwise, if meshing is sucessful look for very skew cells.
