Hi Shawn, Minimum compliance optimizations and, to some extent, stress-based optimizations of static structures are so well studied that developing libmesh code to solve those problems is a bit excessive. These optimizations are already implemented in most of the common commercial FE software packages; ANSYS, for example, has a great topology optimizer that can do both compliance-based and stress-based optimizations and takes minutes to setup. I can tell you from experience that developing your own code will require way more time than using a commercial solution.
