For now I don't wanna capture the 3D effects of the flow, only to chose the most adequate boundary conditions. So, why should I use a periodic boundary condition in the side walls instead of, for...

In short, I'm running a test simulation of flow over a flat plate. I'd like to set correctly a simulation using openings with static pressure condition on the left, right, top and forward boundaries...

Hi,
I just tested it, and it worked fine for the vertical boundaries. But I'd like to use an opening condition on the superior boundary as well (perpendicular to gravity), but the flow (over a flat...

Buoyant flow

Hi,
anyone know the correct way to set up a buoyant flow simulation with static pressure boundary conditions? The problem is how to set the correct pressure profile along a boundary, since (if the...
