Re: About ConvectionBC
Dear steed 188,
I still believe that you want a “normal” pressure outlet condition (Dirichlet pressure=0)? It is possible to set a periodic boundary the only condition is that your outlet has an equal size like your outflow. You have to apply a forcing area instead of the inlet and force your massflow concerning a mean massflow. This is stable for high Re number flows. If you come to the spring School I will show you how to stabilize your case.
Best,
Marc
