Re: [deal.II] Please explain the projection method (tutorial step-35)

In step-35 we find u^{k+1} (diffusion step)
Then we find \phi^{k+1} (projection step) and correct p^{k+1} pressure.
But why we don't correct u^{k+1} velocity? I think u^{k+1} must be solenoidal
but it is not.
Alexey,
I'm not enough of an expert on projection methods, but you might want to try
the review paper by Guermond from a few years ago to get some of the
background of these methods. I don't know whether u^{k+1} must be solenoidal,
but it is quite possible that it doesn't have to be -- only that the
divergence is small (some power of h).
