Synopsis
#include "petscksp.h" 
PetscErrorCode  KSPSetDMActive(KSP ksp,PetscBool flg)
Logically Collective on KSP
Input Parameters
|  | ksp | - the preconditioner context | 
|  | flg | - use the DM | 
Notes
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.
