Abstract
Two tetrahedral mesh refinement algorithms proposed by Zhang are compared u sing the new singular value criterion for the element edge shape matrix. Th e 'short-edge subdivision' scheme is better than 'labeled edge subdivision' . Validity of the singular value criterion is confirmed and its geometric i mplications are investigated.
