Good idea. I think testing against the literature is the correct approach for the test case. > Obviously, having such a convective term would be great if it makes such a > difference :-) For sure. > Also a result of fluent here: > http://www.cfd-online.com/Wiki/Lid-driven_cavity_problem on a 32x32 grid, > but it is not written what order or method is used or how long the > computation took.

I will give it a shot when I get a free day and see what I can cook up.

It will be interesting to see when when we have that functionality in fipy. -- Daniel Wheeler
