[Paraview-developers] Writing exodus files

[Crossno, Patricia J]

My goal is to read in an exodus file, keep only the topology of the mesh (discarding any node or element variables), add some new variables to all of the nodes, and write the resulting mesh and new variable arrays out to a new exodus file.  The problem that I am having occurs in vtkExodusIIWriter::WriteVariableArrayNames() in the call to ex_put_var_param(), which ends up as "Error: failed to define number of nodal variables in file id %d".
