PetscOptionsPush#
Push a new PetscOptions object as the default provider of options Allows using different parts of a code to use different options databases
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscOptionsPush(PetscOptions opt)
Logically Collective
Input Parameter#
opt - the options obtained with
PetscOptionsCreate()
Notes#
Use PetscOptionsPop() to return to the previous default options database
The collectivity of this routine is complex; only the MPI ranks that call this routine will have the affect of these options. If some processes that create objects call this routine and others do not the code may fail in complicated ways because the same parallel solvers may incorrectly use different options on different ranks.
Developer Note#
Though this functionality has been provided it has never been used in PETSc and might be removed.
