Hello.
Thanks for your interest in reading my question. The inlet to my domain carries air with some particle. Many BC's are pressure-outlet BC's. I would like to solve to find the concentrations, while pressure-outlet BC, asks to specify the concentrations at these BC's. Do you have any suggestion that how I can solve this problem? Thanks, Mazyar |

The species concentration specified at pressure oulet will used oly if backflow happens.

Thanks for your replies, even when they are used when there is backflow, how can I know the concentrations on the boundaries? That is my uknown of the problem.
Thanks, |

2 Options ...
Provide better guess for concentration at oulet based on engineering judgement or Extend the outlet so that backflow would not happen and fluent will not use those data. |
