Default Combustion chamber calculation

Hello! I am trying to calculate combustion chamber via CFX-5.6. And I faced great problems. It is impossible to get converging solution - solver has made 500 steps already with physical timescale equals 0.002[s] but all residuals are still high. I have tried to rise timescale and set it equal 0.02[s], but to my surprise nothing changed neither for the better nor for the worse - it was look like as CFX didn't take into account physical timescale at all and used his own one. On the other hand, the same combustion chamber was calculated in another CFD-code successfully and it took 200 timesteps with timescale 0.002[s].

May be someone faced the same problem already?

All recommendations will be highly appreciated.

Thank you in advance. Kirill.
