It *shouldn't* take that
Dear all,
I think we have two ways to do this.
The first one is the way Prof. Wolfgang Bangerth suggested.
The second one is to load the grid in a Triangulation in all processor,
then we set the material id before copying
parallel::distributed::Triangulation from the Triangulation.

Bhanu,
I have looked at 'VectorTools::compute_nonzero_normal_flux_constraints'.

Hello,
I am currently trying to work on a "HPC-ready with Trilinos" version of
step-57 for steady-state solution of the Navier-Stokes equation since I am
curious about compairing it to our stabilized solver. I think that it
could give much better results for steady-state.
