PetscViewerHDF5SetBaseDimension2

 Vectors of 1 dimension (i.e. bs/dof is 1) will be saved in the HDF5 file with a dimension of 2.

Synopsis

#include "petscsys.h"   
#include "petscviewerhdf5.h"   
PetscErrorCode PetscViewerHDF5SetBaseDimension2(PetscViewer viewer,PetscBool flg)
Logically Collective on PetscViewer

Input Parameters

viewer - the PetscViewer; if it is not hdf5 then this command is ignored
flg - if PETSC_TRUE the vector will always have at least a dimension of 2 even if that first dimension is of size 1

Options Database

-viewer_hdf5_base_dimension2 -turns on (true) or off (false) using a dimension of 2 in the HDF5 file even if the bs/dof of the vector is 1

Notes: Setting this option allegedly makes code that reads the HDF5 in easier since they do not have a "special case" of a bs/dof of one when the dimension is lower. Others think the option is crazy.
