hi

I'm currently trying to solve a low-speed flow (using Fluent), through a channel with wall temperaure gradients. I expect the equilibrium solution is periodic. I'd like to know if pressure inlet and outlet conditions at the ends of the channel can be set as initial conditions rather than boundary conditions (i'd like them to change if necessary as part of the iterations and not be held constant).

Excuse me, jay, to not answer, but to ask you a question. Can you please give me a reference to the source, where it is described why do you expect periodic boundary ? Thanks, Pavel.
