A unified approach to remeshing strategies for finite element h-adaptivity

In h-adaptivity, a remeshing strategy is needed to compute the distribution of required element size using the estimated error distribution. Several a uthors have introduced different remeshing strategies yielding Very differe nt results. In this work these methods are included in a unified framework, emphasizing the role of the underlying hypotheses. Moreover, an objective tool to evaluate the accuracy of the resulting finite element solution is p resented. Thus, a new remeshing strategy is introduced to optimize the accu racy of the adapted solutions. The different remeshing strategies are compa red with well-known numerical examples.
