Here are my efforts to implement a mass-flux boundary condition. It seems to have improved convergence stabilty for rhoSimpleFoam, but doesn't seem to do the right thing for potentialFoam.

Since k/epsilon at the inlet are unknown a priori for the mass-flux bc, I've also attempted an implementation for turbulent intensity and turbulent length boundary conditions.

The fact that the integral bc doesn't work at all for potentialFoam makes me wonder a bit though. Perhaps someone will spot the problem.

I've followed the motto "release early and release often" with the hopes that someone else will find the boundary conditions useful.
