PetscOptionsInsertString#

Inserts options into the database from a string

Synopsis#

#include "petscsys.h"   
PetscErrorCode PetscOptionsInsertString(PetscOptions options, const char in_str[])

Logically Collective

Input Parameters#

  • options - options object

  • in_str - string that contains options separated by blanks

The collectivity of this routine is complex; only the MPI processes 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.
