[dune-fem] Direct sum of spaces

[Agnese, Marco]

Hi everybody,

I need to assemble an operator over a direct sum of 2 spaces (namely P1 Lagrange continuous and P0 Lagrange discontinuous).

Is there a support for such spaces in dune-fem? Is there anyone which have dealt with the problem?Do you have any suggestions on how to implement it?

Thank you,
cheers,
Marco.
