Synopsis
#include "petscksp.h"
PetscErrorCode
KSPHPDDMSetType
(
KSP
ksp,
KSPHPDDMType
type)
Input Parameters
ksp
- iterative context
type
- any of gmres, bgmres, cg, bcg, gcrodr, bgcrodr, bfbcg, or preonly
Notes
Unlike
KSPReset
(), this function does not destroy any deflation space attached to the
KSP
. As an example, in the following sequence:
KSPHPDDMSetType
(ksp, KSPGCRODR);
KSPSolve
(ksp, b, x);
KSPHPDDMSetType
(ksp,
KSPGMRES
);
KSPHPDDMSetType
(ksp, KSPGCRODR);
KSPSolve
(ksp, b, x); the recycled space is reused in the second
KSPSolve
().
