[Gmsh] gmsh mesh gives "Degenerate 3D element" error in Elmer

[Zenker, Dr. Matthias]

Hi,

I have a problem with a 3D mesh generated by gmsh: I get a Degenerate 3D element" error when I use this mesh with the Elmer FEM software. The mesh is produced when I mesh the attached geo file , just using the default settings in gmsh (2.6.2-svn, Windows XP).
My questions are:

1.      How can I find out if there are degenerate elements? Is there a way to check the mesh quality in gmsh?
2.      What can I do to avoid degenerate elements?

Thank you for helpful hints,

Matthias
