Hi all

This may not be a deal.II question but I am hoping there may be some nice
solution already available in deal.II

I need to use the cell size h in the dissipation term of a DG scheme. For
adapted grids or non-uniform grids, the cell size varies in a discontinuous
way, which affects the solution, since now the numerical dissipation varies
in a discontinuous way. Is there any simple way to construct a smoother
function h(x) which gives the cell size variation.

I could start with a FE_DGQ(0) function for the cell size and then project
this to FE_Q(1). Is there any better solution, and is there a shortcut (some
available function) that does this ?

Thanks
praveen
