Abstract

In this article the Sub-domain Generation Method (SGM) previously developed for finite element meshes composed of triangular elements is generalised to account for meshes composed of arbitrary quadrilateral elements. A neural network of enhanced accuracy was developed to predict the number of quadrilaterals generated within each coarse quadrilateral element after refinement using an adaptive re-meshing procedure. Partitioning of the meshes was undertaken on the coarse mesh using a genetic algorithm to optimise the partitions considering both load balancing and interprocessor communication of the subsequent finite element analysis. A series of examples of increasing refinement were decomposed by considering a single coarse mesh of a fixed number of elements. © 1999 Elsevier Science Ltd and Civil-Comp Ltd. All rights reserved.
