Hi there,
I am looking for some general assistance with regard to setting up some boundary conditions for internal flow. I have had success with setting up my cases with: U Inlet: fixedValue Outlet: zeroGradient p Inlet: zeroGradient Outlet: fixedValue However, I now wish to fix the pressure at the inlet and perform analyses on what impact the varying inlet pressure has on the system. Unfortunately I have had no success so far in this regard and would be extremely grateful if anyone has any experience setting up a case in this way is willing to assist. Any information would be great. Cheers |

P: pressure-inlet-9 { type fixedValue; value uniform 0.2; } U: pressure-inlet-9 { type pressureInletVelocity; phi phi; rho rho; value uniform (0 0 0); } or { type pressureInletOutletVelocity; value uniform (0 0 0); } |

I am also trying to solve same same internal flow problem using simpleFoam. I am facing a problem. My solution is not converging. Residuals goes upto 0.01. I wanted to ask you which boundary conditions have you used for wall for both parameters. Thank you |

Hello. For the purpose of the modeling of the atmosphere (doors, windows) good results give the BC totalPressure with the value 101325. May be this BC with the different values will be usefull for you case.
