Abstract

Theanalysis of a practical problem using numerical methods such as Finite ElementMethod (FEM) or Boundary Element Method (BEM) involves the subdivision of thespace occupied by a physical system (named domain) or its boundary intosub-domains or sub-boundaries called elements. This task, known as meshgeneration or domain-discretization, is no more trivial if domains of real orindustrial problems involving shape irregularities, various different materialswhich may be non-linear or an-isotropic; are to be taken into account. In thispaper an easy mesh technique considering even domains, which are tiresome handlebarby Computer Aided Design (CAD) Software, has been proposed to achieve efficientand suitable meshes to minimize the computer storage requirements, thecomputation time; and to improve the accuracy of the results during numericalAnalyses. The basic elements adopted in mesh are d-Simplexes.
