mauz is on a distinguished road
Hello everybody,

I'm solving the N-S equations using the SIMPLE algorithm.
It converge fine and quite fast when I set dirichlet boundary conditions for the velocity at inlet and outlet of the channel, but I have problems when I want to set dirichlet B.C. for both pressure and velocity at the channel inlet.
I'm solving the u-momentum equation at the main control volume interfaces, and the pressure correction equation at the central nodes. how should I set the pressure value on the first node, in order to fulfill the inlet pressure condition? I think the problem is there.

thanks in advance

Mauri
