Hello, I'm new to Solidworks and I'm working on a project which I want to study on the flow direction of air inside a fluidic flip-flop. I have designed the flip-flop by myself using surface, knitting it and thicken it, the next thing I do is using flow simulation to study the flow but I have no idea how to continue for now. I have set the inlet flow, outlet pressure, and surface goals, but Im getting warnings like "Vortex appears" and "Supersonic flow exists", would appreciate so much for anyone who willing to teach me. Thank you.
