Engineers who are familiar with finite elements very often ask why it is necessary to develop yet another computational technique. The answer is that finite elements have been proved to be inadequate or inefficient in many engineering applications and what is perhaps more important is in many cases cumbersome to use and hence difficult to implement in Computer Aided Engineering systems. Finite Element (FE) analysis is still a comparatively slow process due to the need to define and redefine meshes in the piece or domain under study.
