karwendel New Member Michael Hopfinger Join Date: Mar 2017 Posts: 14 Rep Power: 9	Dear all, is there a chance to apply 2 boundaries conditions to one mesh 2D region? For example I have got a round outlet but the flow is only allowed to flow through the upper semi-circle and the lower semi-circle is treated like a wall? I want to avoid to use a know mesh. I was thinking about a user surface but don't know how to apply a boundary condition to it. Thank you.
