Hexahedral Mesh Smoothing by Means of Particle Swarm Optimization

Abstract

The main aim in this work is the smoothing and improvement of all-hexahedral mesh (especially created for the finite element method) by means of the particle swarm optimization (PSO) technique. The optimization is performed by using various objective functions derived from several hexehadral element quality metrics. The proposed method is tested over some problems encountered in the electromagnetic theory.
