I try to simulate reduction of pressure in an air tank with rhoPimpleFoam. In the air tank the pressure is 9 bar and the surrounding is 1 atm. I got problem with the solver in the begining of the simulation for T < 0.001 s. i think this is related to a small region with high pressure gradients initial. I dont know if there is any ways around this issue? The error message is shown below. My temperature diverge completely. I use rhomin rhomax 100 and 0.5 kg/m3
