understand of SIMPLE

houkensjtu · July 11, 2011, 08:55

HI,I'm a graduate student and in order to coding my own SIMPLE program I read many samples.
It was a big surprise that some programs do not really solve the momentum equation,but instead,use a unsteady process to solve the problem.(i.e. vel.new=vel.old+dt*(...)).It seems that it also works!
Is this still a SIMPLE method?Can I find any reference which introduce this kind of solving method?
Thank u for your help!

Hi, houkensjtu
The book " An introduction to computational fluid dynamics, the finite volume mehod " of author HK Versteeg and W Malalasekera can help you. There are a lot of detail steps of SIMPLE algorithm.
