How to create a composite boundary? OF5.x

deepbandivadekar · April 12, 2018, 06:24

Hello,

As the title suggests, is there any way to create a composite boundary? I want a particular boundary to act as an inlet as well as a wall. Is this at all possible? Physically this would mean that there's a constant fluid flux out of the patch while strictly preventing any flux into it and active no-slip condition.

Does a boundary patch already satisfy this? If not is there any way to create this?

You could use the inletOutlet boundary condition to prevent inflow where your outlet ist (or outletInlet for the opposite direction).
Not sure if that is what you are looking for, tho.

No no, that's not what I want. I have a porous inlet so it will also act as a wall. But I am looking for a boundary patch for both these conditions. How do I do that?
