Pimplefoam fvSolution
Hi foamers,
there are some things in fvSolution when I use pimplefoam that aren't very clear. For example i don't know if I have deactivate correctPhi or no and if yes, why? The only benefit is less time for convergence or are there more? what is utility set in solvers Phi and pcorr? p.s. what about momentum predictor? Is accounted in correctPhi or is another thing? Need deactivate or not? |
Hello,
I suspect your questions are to general for getting an useful answer. For example, I pick out the correctPhi question: From correctPhi.H header file you get the description: Quote:

Hi,
as Kate already pointed out it is not always needed. I prefer to use it for mesh motion but in general I am always only interested in the capabilities of FOAM so my results accuracy are not of main interest. There are much more key's you can set in the fvSolution subDict PIMPLE. If you are interested in some keywords, you can also check out that one: http://www.cfd-online.com/Forums/blo...orithm&u=25876 I think it is a bit out-dated but it is still valid. I could renew it but there is no time, like always. Good luck and for further questions, I am sure kate can give you good answers. I just wanted to bring a few new informations to you related to the PIMPLE algorithm |
