Hi all,

I am trying to simulate compressible flow in gas-solid fluidised beds using Eulerian multiphase model. The operating pressure is 1000 Pa and I am choosing "Ideal Gas" as material property for only air. The problem I am facing is that the solution is diverging in the first time step itself and the temperature increases to a very high value.
Has anyone ever tried to use compressible flow in eulerian multiphase model? If yes, please suggest where am I going wrong.

Thanks,

Apurv
