Starcatcher Member Andy Join Date: Jul 2017 Posts: 62 Rep Power: 9	hi folks, with interFoam, I need a baffle which lets everything through (incl. water) but keeps a certain velocity. i think baffles can be cyclic, wall or patch. which of those shall i choose? What boundary condition would i choose for example for alpha.water? my favourite approach is using patch, then in U using permeableAlphaPressureInletOutletVelocity. However. For alpha.water i chose zerogradient for the baffle. It did not really work. the water did not ger through. Help please!!
