Hi,

I am planing to model air flow around a barrel which has a couple of openings. Basically air flows around the barrel. Some air can go into the barrel through the openings on the barrel wall facing the inlet air. And, some air can leave the barrel via the openings located on the other side of the barrel facing the outlet.

I would like to use COMSOL, but I do know how to setup my model. Specifically, I do know what sort of boundary conditions I need to use for the openings located on the barrel.

Thanks

So you don't want to model the flow inside of the barrel?

Yes, I would like to model air flow around and inside the barrel.
