manuels is on a distinguished road

i read some facts about the Simple algorithm. In fluent it is also possible to set the SIMPLEC and the PISO method. I cannot understand what is there the exactly difference between then and which i should use in an special case? Can somebody give me material besides Fluent user guide or give me a explanation about them?

RodriguezFatz will become famous soon enough
Use any of them. If it doesn't converge, try another one. If it converges, hooray!
I usually start with SIMPLE, this should work in 90% of all tries.
