Carola Guest Posts: n/a	One more time Robin!, I got a couple of questions to you: 1)What do you mean when you say:"... An error correction is solved on each of the coarser grids and passed back up to the finer grids to improve the solution..", I understood like with every iteration the error is reduced until it reach the tolerance value..., I´m wrong?.Where this error correction come from?. 2)What is the diference between time step and iteration?. Sorry if I made a lot of stupid questions but I finally found someone who can explain to me this kind of things in a very simple way ! Take Care, Carola
