Hi,
i want to model an aerated tank with a degassing outlet. I read in the forum that this can be achieved by using the freestream BC, however if i specify in U.air the outlet patch as : outlet { type freestream; } i get the error message "keyword freestreamValue is undefined in dictionary /xxx/0/U.air.boundaryField.outlet" when using twoPhaseEulerFoam solver. What does this mean? I'm using OF 3.0.1. Thanks a lot! |

Bumping this, I'm running into a similar error. It looks like there was a variable change from 2.X->3.0 but I'm not sure what the correction is
edit: Passing it both freestreamValue and value worked. This is my nut file but U is similar. Code:
boundaryField { airfoil { type fixedValue; value uniform 0.014; } frontback { type empty; } inlet { type freestream; freestreamValue uniform 0.014; value uniform 0.014; } outlet { type freestream; freestreamValue uniform 0.014; value uniform 0.014; } topbottom { type freestream; freestreamValue uniform 0.014; value uniform 0.014; } } |

Hi ss32,
I am also trying degassing outlet. Can simply use Slip BC for the liquid and pressureInletOutletVelocity BC for the gas at the degassing patch? |
