[dune-fem] Mixed boundary conditions

[Mauro Pagani]

Hi,

I'm trying to solve a problem on a square shape domain with mixed boundary conditions, with Dirichlet on top and right sides of the square and Neumann on the other two sides.

The first idea I thought is to enumerate all the nodes such that Dirichlet points have an index separated from the others (that is, if a side is divided into n parts, then all free nodes have index from 0 to (n*n)-1, while Dirichlet points have index from n*n a (n*n)+2n)

Is that a possibility or could DUNE make something different?

Thank you for your disponibility,

Best,

Mauro
