[petsc-users] import a mesh.

[Olivier Bonnefon]

Hello,

Thank-you, I'm using DMPlexCreateFromCellList(), and it works except for 
the boundary conditions.
I'm using Dirichlet boundary conditions, and the corresponding degree of 
freedom are not substituted (like when I use DMPlexCreateBoxMesh).
So, I do have missing a step to define the boundary ?
