Hello, I'm making a flow simulation of intake manifold of car, it contains few parts (throttle, intake manifold and cylinder head). When I try to add point goal in channel of manifold, which is in computational domain, I received a error "Point is out of valid region.". When I add it in the channel of cylinder head (few milimeters further) there is no error. I can also add a points goals in upper part of intake manifold with no error. What causes this kind of error?
Thanks in advance
