Default GAMBIT Question

When I mesh my geometry I get the message initialization failed perturb boundary nodes and then after that the mesh attempt fails and says that there are problems in the face meshes. Well when I do a face check my skewness is below the default. Is there a way that Gambit can tell me where these perturb boundary nodes are rather me go and remesh each edge and then face which is rather time consuming. Thanks

Some methods to solve this problem: 1.smooth your geometry to avoid small gap 2.try to use small grid size 3.adapt your mesh from dense to rare with gradual rate

Well my geometry contains over 1000 faces, therefore many more edges to be meshed. I have tried to mesh each edge and then the face to see how they look. But at the end when all faces are meshed I check them and Gambit says none have failed. But when meshing the volume I get the error. How can the faces can no skewed elements, but the volume says there is and therfore can't mesh the volume. I saved the boundary mesh and opened it in Tgrid. When I try to mesh there it keeps stopping and tells me to delete nodes and remesh. I have done this many times. There must be a better way. I have tried to make my mesh coarse as possible without having skewed elements. My geometry is exported as a parasolid from Unigraphics. Once imported into Gambit it is one volume. I have tried to clean the geometry in Gambit by deleting the volume into faces, but once I try to reheal the faces to become a volume it won't let me. If I could do that I can eliminate a lot of faces. If anyone has suggestions it will be helpful.
