Hi Matt, this is a follow-up to the previous question:
I have created a short code as below to create a sub-dm on the surface,
extracted from the original volume dmplex:
-
call DMClone(dm_origin, dm_wall, ierr);CHKERRA(ierr)
! label for face sets
Thank you Jed and Matt. That is exactly what I wanted to do.
I was wondering if there is an example of mapping between DMPLEXs.
I have several requirements of the mapping for my code, such as
- mapping solution vectors on cell-centroids into vertices
- mapping from volume dmplex into sub-dm for
Yes, you can use DMPlexCreateSubmesh() (and friends depending on exactly
what kind of submesh you want). This will allow you to create a vector over
only this mesh, and map your volumetric solution to that subvector. Then
you can view the subvector (which pulls in the submesh).
Thanks,
I would create a sub-DM containing only the part you want to view.

Hi,
I am a user of DMPlex object in 3D grid topology. Currently the solution
field is printed out using viewer PETSCVIEWERVTK in .vtu format. By doing
that the entire volume components are written in the file. I was wondering
if there is an option that I can tell PETSc viewer to print out only
