cramr5 Member Marc Ricart Join Date: Jul 2022 Posts: 65 Rep Power: 3	Hello, I am trying to model the impact of the pressure increase in a "box" when a sudden burst of gas is released into it. The thing is that for outlet we will have a "valve" that will only allow flow out when internal pressure is above 100mbar. The thing is I don't know how to model that, If I use Pressure Outlet with a pressure of 100mbar the simulation goes crazy and diverges... Any idea how? shoud I use a porous media effect? Thanks
