This paper describes an enhanced error estimator for adaptive ®nite element analysis of three-dimensional incompressible viscous ¯ow. The estimator uses a modi®ed form of the recovery functional employed in the well-known L 2 local patch recovery technique (LPR) originally proposed by Zienkiewicz an
Procedures to enforce equilibration of residuals and determine complementary a posteriori error estimates for linear elasticity have been published elsewhere. Methods for determining the error in stress and displacement have also been proposed. Here we discuss an extension to the procedure for equi
