DMGetOutputSequenceLength

Retrieve the number of sequence values from a PetscViewer

Synopsis

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMGetOutputSequenceLength(DM dm, PetscViewer viewer, const char name[], PetscInt *len)

Input Parameters

• dm - The original DM

• viewer - The PetscViewer to 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
