Porous jump BC

Hi everyone
I'm trying to simulate the flow inside a tube which has a specific injector. In my experimental set up, the tube is closed with a paper filter. In this way I have 3 BC : a pressure inlet (0.5bar overpressure), a porous jump and a pressure outlet(atmospheric pressure). My simulation is running for incompressible flow, but for compressible flow I always have the message :"divergence in amg solver : temperature". I've tried a lot of solutions I found on this forum but I've still the same problem. Does someone have an idea???? |

Have you tried with a little under relaxation factor on the energy equation? I`m working too on a similar project, with pressure jump...it doesn`t work very well...
