Indicates the DM should be used to generate the linear system matrix and right-hand side vector
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPSetDMActive(KSP ksp, PetscBool flg)
Logically Collective
Input Parameters#
Note#
By default KSPSetDM() sets the DM as active, call KSPSetDMActive(ksp,PETSC_FALSE); after KSPSetDM(ksp,dm) to not have the KSP object use the DM to generate the matrices.
