Has anyone done any benchmarking with dolfin?
I've been comparing some dolfin output to some problems I've
previously done using COMSOL and I have to tell you I'm not crazy
about the results. In particular, I'm interested in linear Stokes
flow problems around objects that arise out of homogenization and I
find that when I compute the domain averages of the variables
( pressure, velocity ), as one does in such problems, the convergence
to a fixed value as the mesh is refined isn't so good. I've tried
both iterative and direct solvers too.
