Could you provide a small code which demonstrates the problem? Elem::contains_point can give false positives (due to floating point geometry and tolerance-based comparisons) near element boundaries, and on a sufficiently distorted second order mesh I guess it might be able to give false negatives (due to inverse mapping Newton tolerances) but under no circumstances should it be non-deterministic! --- Roy ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
