PCSetFromOptions#

Sets PC options from the options database.

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCSetFromOptions(PC pc)

Collective

Input Parameter#

  • pc - the preconditioner context

Options Database Key#

  • -pc_type - name of type, for example bjacobi

Notes#

This routine must be called before PCSetUp() if the user is to be allowed to set the preconditioner method from the options database.

This is called from KSPSetFromOptions() so rarely needs to be called directly
