Dear all,
I am trying to set up a case with the solver buoyantPimpleFoam, but I can't make the simulation start. Attached a test case. If you launch it (execute the blockMesh, first), you get an error. Immediately. Could you have a look? Thanks a lot, Samuele |

This is the error that you get, when launching the solver:

Hi,
here is an other test case for you. Maybe you compare with your case... Bye Tian |

Hi Tjan,
I can't open the archive. It seems corrupted. Could you check it, please? Thanks a lot, Samuele |

Hi,
it s not possible for me to test your case but set a value in the file p: Code:
inlet { type buoyantPressure; value $internalField; } That is the only hint at the moment |

I am working on buoyantPimpleFoam case. I prepared a wedge shaped geometry and using almost similar setting as of hotRoom tutorial. As the simulation is started the deltaT starts decreasing and keep continue to decrease and reaches upto the power of 1e-5/6 and then it stop with an error message of "iterations exceeded". Is there any possible way to run a stable simulation with buoyantPimpleFoam. working on OF 2.2.x Regards, Jamal |
