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 beNULL
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.
