combustion modeling
 

Hi friends,any one can tell me In combustion modeling how would we find the height of the flame? and What's the meaning of 'divergence detected in AMG solver :temperature' and what's its reason?

Re: combustion modeling
 

hi, when there is a message of divergence detected in temperature the reaspns can be : - an error of the definition of boundary condition, which is the most probable reason.You should check the boundary condition. - a not well defined mesh, you should use a finer mesh - a problem of density law.what kind of density law are you using?

Hi antonietta Thanks for your reply,I use incompressible ideal gas B.C, and when I use a finer mesh this message of divergence didn't detected.

Re: combustion modeling
 

well, so you have solved your problem.I have had the same problem and it was due to the mesh too. good luck anto

HI I FIND U PROBLEM ALSO DO THE INCREASE TEMPERATURE LIMIT IN THE FLUENT WHEN U STARTING INTILIZATION
