VecLoadExodusCellSet

Read a Vec representing the values of a field at a cell set from an exodusII file.

#include "petscdmmesh.h" 
PetscErrorCode VecLoadExodusCellSet(DM dm,Vec v,PetscInt csID,MPI_Comm comm,PetscInt exoid,PetscInt step,PetscInt exofield)

	dm	- the DMMesh representing the mesh
	v	- the LOCAL vector of values to be saved (i.e. with ghost values) obtained with SectionRealCreateLocalVector. if v represents a field with several components, the block size must be set accordingly using VecSetBlockSize().
	csID	- the ID of the cell set
	comm	- the communicator associated to the exo file + if size(comm) == 1 each processor writes its local vector into a separate file . if size(comm) > 1, the values are sent to cpu 0, and written in a single file
	exoid	- the id of the exodusII file (obtained with ex_open or ex_create)

step -the time step to write

exofield -the position in the exodus field of the first component

Interpolated meshes are not supported. -
