[petsc-users] DMPlex submesh and Boundary mesh

[Dharmendar Reddy]

Thanks. The code works.

Now, i need to access the map from points in subdm to points in dm. I need
to use this function right  ?

DMPlexCreateSubpointIS(DM dm, IS *subpointIS)

Fortra binding please.. Also, i was thinking it may be of use to have
interface like this..

DMPlexCreateSubpointIS(DM dm, PetscInt pointDimInSubdm, IS *subpointIS)

this way i can have map from say (dim)-cells in subdm to corresponding
(dim)-cells in dm if a subdm is a lower dimensional mesh.  Of course i can
use the first interface by checking the dim of the point in subpointIs
before using.


thanks
Reddy
