Boundary faces are often labeled already on a mesh, but you can use this to set a label for all boundary faces. https://petsc.org/main/manualpages/DMPlex/DMPlexMarkBoundaryFaces/ "Ferrand, Jesus A." <[email protected]> writes:
Greetings.
I terms of dm-plex terminology, I need a list points corresponding to the boundary (i.e., height-1 points whose support is of size 1). Sorry if this is trivial, but I've been looking at the list of APIs for DM-Plex and couldn't find/discern something that addresses this need.
I guess I could loop through all height-1 points and call DMPlexGetSupportSize() and assemble said list manually. The assumption for the plex I'm working with is that it has had DMPlexInterpolate()called on it.
