[petsc-users] Problems with Gmsh

[Santos Teixeira Frederico]

Hi folks,

Based on ex62, I started a project and I would like to use gmsh.
It seems however that I am missing something, because it works very well with both 2D and 3D meshes from PETSc (with DMPlexCreateBoxMesh), it works quite well with 2D meshes from gmsh, but it fails with the 3D gmsh. Also, the Initial Residual vector for this latter case contains big values, while it is almost zero for the other successful cases.

The full output is attached, along with the code, .msh files and command-line options, where these issues can hopefully be reproduced. Any hint is highly appreciated.

Regards,
 Frederico.
