Hi all,
While using buoyantSimpleFoam in an backwards u like shape i am getting a strange pressure field and no outflow. I guess it must be becouse of the boundary conditions... the boundary conditions are: __________U ________P_________ ____p_rgh _________T Inlet ______fV______ ___calculated ___fFPresuure_____ fV __________uni(-0.8 0 0) _____________gradient 0 _____uni 343.15 _________________________________value uni 1e5 walls _______no slip _____calculated ___fFPresure _______zG __________________________________gradient 0 _________________________________value uni 1e5 0utlet ______inletOutlet__ _calculated____ fixedValue_____ inletOutlet ________inletValue uni (0 0 0)_ _________uniform 1e5_____iV uni 343.15 __________value uni (0 0 0) __________________________v uni 343.15 Im greatfull for any help. |

Hello David,
Could you please clarify what you are asking? Are you asking why the high pressure is occurring, or what boundary condition is causing this? |

Hi Kira,
I am asking both, and most of all, how to fix it. Thanks, David |

Hi,
I found a solution, in witchthe flow was perfect eventaugh ithink there would be a nicer solution. I put the gravity to 0. |
