I don't know of any examples offhand, but this conversation belongs on libmesh-users anyway and perhaps someone else there will chime in. The libMesh solver interfaces have an attach_preconditioner method, which you can use to supply your own preconditioner matrix. It looks like we might only support SparseMatrix preconditioners, not ShellMatrix preconditioners, but if you want to do the latter then that interface (for use with PETSc, at least; I don't know if we ever got around to adding ShellMatrix support for other solvers) shouldn't be too hard for you to add. --- Roy ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
