[aspect-devel] Progress in writing the mantle convection code Aspect

> We're quantifying them for an AGU poster so we'll have more information then.  If I recall correctly, they are on the order of 5-10% of the gradient (so for a gradient of 10^4, the overshoot would be on the order of 10^2 to 10^3), versus up to 20-30% for CitcomS.  Finer resolution will make them more localized but generally worse in magnitude.

If you can set up simple to run examples, I am interested in seeing
them. You can likely remove overshoots by increasing the stabilization
parameter beta. What is your compositional field supposed to
represent?
