Hi, I have prepared a 3D mesh in GAMBIT and used the matlab converter to make the .rea and .map file. When I use these files for computation, things appear to go on nicely and the flow field that I get is not different from what I expect. However, I notice the following lines in the output file which says that the geometry has been regenerated. What does this mean? Would it comprise the quality of the mesh near the wall?
