Error: divergence detected in AMG solver: temperat
 
I am obtaining this message in the solver: Error: divergence detected in AMG solver: temperature

Why? What this mean and what I am doing wrong?

Thanks,

Rubén Meza

Dear Sir or Madam, In order to simulation of turbine blade film cooling,I encountered the same error in fluent.It would be so nice of you to reply me.

Best Regards, Pegah Pezeshkpour

Re: Error: divergence detected in AMG solver: temp
 
hi.. if in your problem the maximum temperature value is greater than 5000K.. (default value inj Fluent ) it wil show divergence. so you can go the solutions- limits option to increase the max. temperature.. or \ if not you try to solve your problem first deactivating energy equation .. and once flow is converged activate the Energy eqn,, and start running it. hope this wil meet ur ques, plz let me know.. the result.

Hi,thank you for your reply.The default Temp.in Fluent is 300K.mine is 153 & 302K.Even if I deactivate energy equation this happens!! Could it be related to the Mesh in Gambit?even it was successfully exported to fluent?!
