! !DESCRIPTION:
!   Write a mesh to VTK file.
!
!   \begin{description}
!   \item [mesh]
!         The mesh.
!   \item[filename]
!         The name of the output file.
!   \item[{[nodeArray1-3]}]
!         Arrays built on the node location of the mesh
!   \item[{[elemArray1-3]}]
!         Arrays built on the element location of the mesh
!   \item [{[rc]}]
!         Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
