grid-convergence with Stokes uses relaxation? #1

Closed labarba closed 9 years ago

labarba commented 9 years ago

The first result in the section on Stokes equation presents a grid-convergence study. I would expect that to be using the regular, non-relaxed GMRES iterations. But the Caption says: "Convergence of first-kind equation for Stokes flow around a sphere. Initial $p=16$, linear system solved to $10^{-5}$ tolerance."

Initial p sounds like relaxation was applied. But was it?

I really can't remember -- I think this is a typo, and the runs were performed with p=16 for all steps (and I know for a fact that I performed the convergence study both with relaxation and without, in order to make sure I wasn't missing something that should give me 1/N convergence, and got the same results for both cases).

I did think that it is likely a typo. I'll edit the caption.
