hi everyone
i have a simulation of two different fluids, flowing inside a tube and one outside. i set the simulation with k-e model and pressure based, the time is steady. the problem is that it report reverce flow in __ faces on outflow. the boundary condiction is: two velocity inlet and two outflow. then step of simulation is inizializate all zone. what did i do wrong? thank you |

Hi
check for the outflow bondaries locations. its better to set outflow in fully developed region. if your outlets are in developing region use pressure-outlet condition. else, this is a warning and should be disappear. Regards, |

thank you,
tomorrow i try the simulation with a boundary condiction on outlow pressure. |
