Synopsis#
#include "petscpc.h"
PetscErrorCode PCSetDM(PC pc, DM dm)
Logically Collective
Input Parameters#
Note#
Users generally call KSPSetDM(), SNESSetDM(), or TSSetDM() so this is rarely called directly
Developer Notes#
The routines KSP/SNES/TSSetDM() require dm to be non-NULL, but this one can be NULL since all it does is
replace the current DM
