Hello,
I have a fundamental question regarding two methods PISO and a doubleSimple scheme.

simple 1) solve u* (u,v,w) based on guessed p* -> update p' (using u*)-> update u=u*+u', p = p*+p'

piso : (1) solve u* (u,v,w) based on guessed p* -> update p' (using u*)-> update u=u*+u', p = p*+p'
(2) solve u** based on p* -> solve p'' -> update u**=u*+u',p**=p*+p'

is piso a two time SIMPLE per iteration?

Thanks,
