PetscOptions#
PETSc’s runtime options database object; the holder of all PETSc command-line and configuration options for a session, looked up via PetscOptionsGet*()
Synopsis#
typedef struct _n_PetscOptions *PetscOptions;
Notes#
Most PETSc API calls accept NULL for PetscOptions, meaning “the default global options database”. Use PetscOptionsCreate() / PetscOptionsPush() to manage non-default databases (e.g. when reading options from a file).
Each PetscObject may also carry its own non-default options through PetscObjectSetOptions().
