The problem of ÿnding a nearly optimal distribution of polynomial degrees on a ÿxed ÿnite element mesh is discussed. An a posteriori error estimator based on the minimum complementary energy principle is proposed which utilizes the displacement vector ÿeld computed from the ÿnite element solution. T

✦ Synopsis
Parallel computation on clusters of workstations is becoming one of the major trends in the study of parallel computations, because of their high computing speed, cost effectiveness and scalability. This paper presents studies of using a cluster of workstations for the ®nite element adaptive mesh analysis of a free surface seepage problem. A parallel algorithm proven to be simple to implement and ef®cient is used to perform the analysis. A network of workstations is used as the hardware of a parallel system. Two parallel software packages, P4 and PVM (parallel virtual machine), are used to handle communications among networked workstations. Computational issues to be discussed are domain decomposition, load balancing, and communication time.

We consider methods for adaptive updating of computational meshes during incremental loading of non-linear shell and solid structures. In particular, we focus on updating methods where the initial topology of the mesh is maintained. The movement of the mesh (the convective step) is decoupled from th
