PCRegister#
Adds a method (PCType
) to the PETSc preconditioner package.
Synopsis#
#include "petscksp.h"
PetscErrorCode PCRegister(const char sname[], PetscErrorCode (*function)(PC))
Not collective. No Fortran Support
Input Parameters#
Example Usage#
PCRegister("my_solver", MySolverCreate);
Then, your solver can be chosen with the procedural interface via
PCSetType(pc, "my_solver")
or at runtime via the option
-pc_type my_solver
Note#
A simpler alternative to using PCRegister()
for an application specific preconditioner is to use a PC
of PCType
PCSHELL
and
provide your customizations with PCShellSetContext()
and PCShellSetApply()
PCRegister()
may be called multiple times to add several user-defined preconditioners.
