✦ Synopsis

An adaptive refinement procedure using a new automatic quadrilateral element mesh generator is presented. The performance of the adaptive procedure in achieving a given accuracy with different mesh refinement strategies is compared. It is found that when using bilinear or biquadratic quadrilateral elements refinement strategies of both mesh enrichment and mesh regeneration can lead to a prescribed accuracy being achieved by the Zienkiewicz-Zhu adaptive procedure with the optimal rate of convergence. However, fewer mesh refinement steps are needed if the strategy of mesh regeneration is employed with the newly developed automatic quadrilateral element mesh generator.

## Abstract Quadrilateral finite elements are generally constructed by starting from a given finite dimensional space of polynomials __VΜ‚__ on the unit reference square __KΜ‚__. The elements of __VΜ‚__ are then transformed by using the bilinear isomorphisms __F__~__K__~ which map __KΜ‚__ to each conve
