PCShellSetPostSolve#

Sets routine to apply to the operators/vectors after a KSPSolve() is applied. This usually does something like scale the linear system in some application specific way.

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCShellSetPostSolve(PC pc, PetscErrorCode (*postsolve)(PC pc, KSP ksp, Vec xin, Vec xout))

Logically Collective

Input Parameters#

  • pc - the preconditioner context

  • postsolve - the application-provided presolve routine

Calling sequence of postsolve#

  • pc - the preconditioner

  • ksp - the KSP that contains pc

  • xin - input vector

  • xout - output vector

Note#

You can get the PCSHELL context set with PCShellSetContext() using PCShellGetContext() if needed by postsolve.
