Thanks, Derek.

A related question about libMesh:   

If I need to output the solution values on the boundary nodes, can I use 
BoundaryMesh along with the IO classes for that? 

Meaning, if I do the following

            BoundaryMesh b_mesh(mesh.mesh_dimension()-1);
            mesh.boundary_info->sync(b_mesh);
            VTKIO(b_mesh).write_equation_systems("boundary_output.pvtu", 
equation_systems);


Would this write the solution values on the boundary nodes?
