Mesh repair. was created by Claude Potard
Hello friends,

I have built a solid from IGES import into Salome Geom module and then meshed it whith success: all controls and checking indicated no problem such as free edges or bad elm. Going to Code_aster wizard linear elasticity, to run the computation this one goes to the end but a lot of error messages came with the result. All dealing with meshing defects: orphan nodes,geometricaly mixed nodes,flat cells or most important , cells with free element de bord.
So as I want to repair the mesh my questions are:

1/ how can I make the link between the bad cells or nodes named in the .mess file of Code_aster module by letters ex. N1N4 for a node , MZ or M20 for Segments or again M9N for TRIA3 cell and their corresponding position into the mesh given by Display entities or numbering defined with number references only ?
2/ how can I identify hese bad entities to correct the mesh using Salome ?
One more question:
3/ I tried post-pro results présentation and obtained this bad message: object cannot be built:diagonale of the actor is too large. I check of course the actor dimensions and do not found too large extensions.

Thank you for your attention

Claude

ps:excuse to one's who read this message on the french forum

This is to say that my request has found a solution:all the error messages coming from code-aster case were caused by singular points of the mesh. In fact a few faces of the geometry were spheric caps with very large radius. So I change tetrahedron mefisto for netgen3d_2 d_1d meshing with success and code_aster works well.
