Abstract

H-adaptive finite element methods for nonlinear transient analysis by explicit time integration are described. General strategies for their implementation and error criteria are presented and discussed. Examples are given of adaptive calculations for simple components and prototype calculations for a full car model. H-adaptivity offers substantial reductions in data preparation costs and improvements in accuracy.
