This is part of your (our) problem, I'm afraid: we don't output any shape functions more interesting than C0 quadratics in any formats that viz software can read. So basically the C1 3-split cubic functions you get with CLOUGH in libMesh get reinterpolated onto C0 1-split quadratic functions. I wouldn't expect the gradients to be continous *anywhere*. There shouldn't be a larger discontinuity than average along partition boundaries, though. That still might indicate a localization bug, either in your code or ours. If it is a problem in library code... I don't suppose there's any chance you could reproduce it with a tweaked adaptivity_ex4 ? --- Roy ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
