AMG solver error
hi all

i am simulating air-kerosene mixing in a scramjet combustion chamber.

i am getting an error as shown below

Error: divergence detected in AMG solver: temperature

what is the reason and what is the rectification which needs to be done?

Re: AMG solver error
try tuning under relaxation factor

Re: AMG solver error
tuning means increase or decrease?

Re: AMG solver error

solve your flow field first without turbulence model, without energy equation or other models (combustion).

Then subsequent turn each model on...
