Actually, before you do that: are you sure you localized the solution before using it to calculate the gradients? That's the only way I could picture encountering a partitioning-specific gradient discontinuity in C1 elements - the gradient components aren't calculated (and thus aren't potentially miscalculated) from some other degrees of freedom, they *are* degrees of freedom. --- Roy ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
