Hi
I'm solving a channel flow including species transport equation. But if I set a under relaxation factor (less than zero(0.9, 0.8, ..)) for a species transport equation, then the speceis mass fraction becomes zero at the channel outlet. how can I solve this problem? |

Hi,
Check your initial conditions... your solver is transient? There's any chemical reaction? If your set the relaxation factor to zero the solution don't advance... |
