HELP !In relaxtion factor converge is taken or not
hi i doing combustion problem. it converge but at the low solution parameter means relaxtaion factor.it taken or not. i started at low value like pressure,energy,tarbulent,and moment and going to default value but in some case like energy it converge at low value but other converge at default vale is this converge is taken or not. please help

Hi
You are able to reach convergence of residuals, isn't it? If so, then whats the problem? Regards, Manoj |
Re: HELP !In relaxtion factor converge is taken or
thanks for reply but convrge at lower than default value is it accept ? it converge but the flue gas temperature is so high. the temperature of combustion at nozzle is 3700 K and flue gas is 3500 K so it is accept as converge solution or not

Re: HELP !In relaxtion factor converge is taken or
Yes. Convergence at lower than default value is acceptable. I would suggest you to go though fluent guide or any text to understand what under-relaxation is.
As far as accuracy of your results are concerned, that is dependent on the flow model and other algorithms that u select , as well as on the grid size and parameters that you input. Manoj |
