PetscErrorCode DMGetOutputSequenceLength(DM dm, PetscViewer viewer, const char name[], PetscInt *len)
Input Parameters#
- dm - The original - DM
- viewer - The - PetscViewerto get it from
- name - The sequence name 
Output Parameter#
- len - The length of the output sequence 
Note#
This is intended for output that should appear in sequence, for instance
a set of timesteps in an PETSCVIEWERHDF5 file, or a set of realizations of a stochastic system.
Developer Note#
It is unclear at the user API level why a DM is needed as input
