Hi,

I am working on furnace simulation.
In my model i set RNG turbulence, energy, DO radiation model and 2 set reaction for combustion and kinetic cracking consist of about 12 reaction in steady state.
Unfortunately fluent case can not reach convergence or good results comparison to actual datas.
I search some posts in cfd-online for setting up solvers (solution methods and control and multigrid solver for cycle type of pressure velocity species and ...).
Also i have these errors:
Divergence detected in AMG solver: species -> Increasing relaxation sweeps
Divergence detected in AMG solver: temperature -> Increasing relaxation sweeps
temperature limited to 5.000e+00003 in xxx cells...
and etc.

Mesh quality ~0.3
Aspect ratio ~15

Please help me until i slove this problem.

Thanks

Please help me, i need your assistance.
