[dune-pdelab] VTKWriter for DG method

[Dmitry Mazilkin]

Hi Amir,

I'm using in DG the following:

using UDGF = Dune::PDELab::DiscreteGridFunction<GFS,U>;
UDGF udgf( gfs, u );

refinement=std::max(dg_degree-1,0);

Dune::SubsamplingVTKWriter<GridView> vtkwriter( gridview, 
Dune::refinementLevels(refinement));
 
vtkwriter.addVertexData(std::make_shared<Dune::PDELab::VTKGridFunctionAdapter<UDGF>>(udgf,"u"));

In your case, I'd expect to do the same for each component.

Best regards,
Dmitry.
