5.1. NLAD-GPAD Benefits

The following figure shows how using NLAD-GPAD (rather than standard nonlinear adaptivity) in a linear analysis improves stress predictions near the boundary of the holes. There is a marked difference in the accuracy of the recovered solution and the true geometric boundary recovery at the bolt holes.
