This is pretty astonishing. Can you get the bad convergence results with -DNDEBUG applied to libMesh alone? If so then we've probably got a bug worth looking into somewhere. I can't imagine where, though. We just don't have a lot of places where there's a significant difference between normal and NDEBUG code paths. --- Roy ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
