I convert a .unv mesh file that was generated by salome to elmer mesh format by using the command:
elmergrid 8 2 mesh
A mesh is created, but when I open it in ElmerGUI the program crashes. The same happens if I start the ElmerSolver.
If I open the .unv in ElmerGUI the file is opened without problems, I can save it in elmer format and simulate it. So I assume that the .unv is ok.
Is there an other way to convert .unv to elmer grid? I need a scriptable solution.
ElmerGrid: Windows XP-Version 5.1.2600

Re: ElmerGrid creates invalid mesh
With the parameter -autoclean the mesh is valid. I do not understand why but it is working.
Re: ElmerGrid creates invalid mesh
Hi,
the ElmerGrid output when you convert the mesh into the Elmer mesh.* format says that your original .unv mesh contains a lot of lower dimensional elements (like, for instance, a 1D element in a 3D mesh). You must clean those degenerate elements before loading the mesh, as ElmerGrid with the flag -autoclean actually does.

Cesar
