[petsc-users] Problems imposing boundary conditions

Fri Mar 17 06:02:57 CDT 2017

I think there might still be another problem, this time it has to do with
DMPlexInsertBoundaryValues. Say we have a simple mesh like this:

4 ---- 5
|  \   1 |
|    \    |
|  0  \  |
2 ---- 3

and we constrain the left face to be 0 and the right face to be 1. The way
it is now, DMPlexInsertBoundaryValues would first insert a 0 at point 2, 3
and 4 and then insert a 1 at point 3, 4 and 5. This is obviously not what
we want, because we don't want these boundary conditions to overwrite each
other. I think the easiest fix for this would be to make the following
changes here:
<https://bitbucket.org/petsc/petsc/src/b479c6a5cd3f3d80d6200abafc21a3a92ac09320/src/dm/impls/plex/plexfem.c?at=master&fileviewer=file-view-default#plexfem.c-444>
remove the calls to DMPlexLabelAdd/RemoveCells and set the maximum
projection height to dim.
But maybe someone (Matt) has a better solution?

Thanks,
Sander
