[Dune] index error

[Sreejith Pulloor Kuttanikkad]

Below are two error messages that I got when trying to get
element index and when using UG grid. I couldnt figure out why.

1) I used to get the element index/id in the following way:

int eid = mygrid.levelIndexSet(mygrid.maxLevel()).index(*it);

 where Iterator it = mygrid.lbegin<0>(mygrid.maxLevel());
but after updating the dune, I get following error message:

/afs/iwr.uni-heidelberg.de/home/sreejith/dune-home/dune/dune/grid/sgrid.hh:

dimworld>::Traits::LevelIndexSet& Dune::SGrid<dim,
dimworld>::levelIndexSet(int) const [with int dim = 2, int dimworld =

2) error message with UG grid

after updating the dune when i try to use UG grid its giving following
error message:
