There appears to be a slight overloading of the nomenclature here... I'm used to "composite finite elements" being a synonym for "macroelements" like the Clough-Tocher triangles, which were practically the first thing I added to the library years ago. But you're referring to something libMesh doesn't have. I assume you mean elements with subgrids, i.e. to build "handbook functions" for discretizing problems with complex fine-scale constitutive fields? > This is a low-priority task; I would just like to see what you guys > think.

CFEs would definitely be welcome, since they ought to be able to fit onto the FEBase API without changing the latter too much. The tricky question is "how do you automatically solve the subproblem" with them... You'd basically have to hot swap an entire new Mesh (and corresponding DoF numbering and algebraic discretizations) in and out from underneath the EquationSystems. Or you'd have to require the user to have an FEMSystem or some other API that provides physics at a non-global level. --- Roy ------------------------------------------------------------------------------ Come build with us!
