Abstract -In this paper, the main methods employed during mesh generation, in order to control element distortion, are reviewed, and some shortcomings are outlined. A new distortion factor is then introduced, which is both simple to implement, and provides a rapid measure of an element's quality. Some meshes demonstrating their use are finally presented.
