Thanks for your replay. The main problem is with the data
communications part after grid refinement. I ran the adaptivity
example example07 from pdelab-howto in parallel and I get a
Instead of using
Dune::PDELab::adapt_grid( grid, gfs, u, 2 );
to adapt the grid I used its implementation from
pdelab/adaptivity/adaptivity.hh to see where the problem is and I
found that the segmentation fault comes when calling the function
I hope it give a better idea of what is the problem I'm facing.
