Hi, Thanks for the quick help. I think I get it now. If/when I get libMesh going, would there be any interest in some plotted examples of toy problems, with code, for the Wiki? I'm thinking of trying some "particleinabox" Helmholtz equation problems and some 3D smalldeformation structural problems.
