[dune-pdelab] Problem with codim 1 iterator and UG Grid

[Dodwell, Timothy]

Hi all,

I am implementing implicit error estimator, which requires me to loop over all entities of codim 1

When I do this, something like

      // Make grid using UGGrid
      typedef Dune::UGGrid<dim> GRID;
      GRID grid;
      Dune::GridFactory<GRID> factory(&grid);
      Dune::GmshReader<GRID>::read(factory,gridName);
      factory.createGrid();
      //grid.loadBalance(newcomm);

      typedef typename GRID::LeafGridView GV;
      GV gv = grid.leafGridView(); // Get finest grid

      typedef typename GV::template Codim< 1 >::Iterator CodimIterator;

      const CodimIterator codimEnd = gv.template end< 1 >();

      int size = 0;
      for( CodimIterator it = gv.template begin< 1 >(); it != codimEnd; ++it )
        {
          ++size;
        }

I get the following error


/home/tjd20/git_workspace/dune/dune/dune-grid/dune/grid/uggrid/uggridleafiterator.hh:141:56: error: invalid conversion from void*' to 'Dune::UG_NS<2>::Entity<1>::T* {aka UG::D2::edge*}' [-fpermissive]

       this->virtualEntity_.setToTarget(UG_NS<dim>::succ(this->virtualEntity_.getTarget()), grid_);

Works fine for codim 0 and 2

Anyway ideas?

Cheers

Tim
