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?

thanks!

try tuning under relaxation factor

Re: AMG solver error
 

tuning means increase or decrease?

thanks

Hi!

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

Then subsequent turn each model on...
