I tried to simulate using rhoSimpleFoam and buoyantSimpleFoam, but I became following problems:

1. The Pressure Solver needs 1000 Iteration per Timestep

2. I canīt find the thermoType below under thermophysicalpropeties
thermoType hThermo<pureMixture<constTransport<specieThermo<hC onstThermo<perfectGas>>>>>;

- could someone send me a case simulated using rho- or buoyantSimpleFoam ?

- I would also like to know how to set alpha, mut, p, T under "0-Directory"

Thank you in advance (It is very important please!)

Hi Ronaldo,

maybe my case help you a little bit. It is for OpenFOAM Version 1.5-dev (bouyantSimpleFoam). It is a small room with 3 inlets and 3 outlets.

Your problem looks like a pressure boundary mistakes (1000 iterations).
