SNESSetDM#

Sets the DM that may be used by some nonlinear solvers or their underlying preconditioners

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESSetDM(SNES snes, DM dm)

Logically Collective

Input Parameters#

  • snes - the nonlinear solver context

  • dm - the DM, cannot be NULL

Note#

A DM can only be used for solving one problem at a time because information about the problem is stored on the DM, even when not using interfaces like DMSNESSetFunction(). Use DMClone() to get a distinct DM when solving different problems using the same function space.
