Inspite of extensive use of finite element methods, the barriers between engineering design and analysis still exist and the way to bridge gap is to reconstitute the entire process. Idea is to use one model and use it as an analysis model which require a change from classical finite element to an anlysis procedure based CAD representation, formally known as Isogeometric analysis. There are several CAD functions which can be used for CAD representation of analysis module. Of most widely used CAD basis in engineering design process are NURBS (non-uniform rational B-splines) as presented by Piegle and tiller, 1 Farin, 2 Cohen et al. 3 and Rogers. 4 NURBS represent a billion dollars CAD industry and are useful for analysis purposes because they possess useful mathematical property of refinement through knot insertion and variational deminishing property of convex hull. In other CAD basis available, T …
