TaoSetDM#
Sets the DM that may be used by some TAO solvers or their underlying solvers and preconditioners
Synopsis#
#include "petsctao.h"
PetscErrorCode TaoSetDM(Tao tao, DM dm)
Logically Collective
Input Parameters#
tao - 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.
