Dear all,
I have big problem about how to set pressure outlet boundary condition. My simulation is about simulation in tank which have ventilation outlet. In this ventilation, I will set it with pressure outlet but I don't know backflow method. May U know what is better method for backflow direction specification method and Specification Method for turbulence.
Thank before.
Regards
Defri

If you have backflow then it is better that you specify pressure outlet at the outlet boundary. Do not use mass outflow in that case.
