Isogeometric FEM with matlab

DESCRIPTION
This matlab code presents an introduction to isogeometric analysis whereby the basis functions that are used for computer aided geometric design (CAGD) are also used for approximation in finite element analysis. The present code uses Non-Uniform Rational B-Splines but it should be noted that the CAGD community is making headway towards other descriptions of the geometry, overcoming the limitations of NURBS such as lack of water-tightness.The code also illustrates enrichment through the eXtended Finite Element Method framework where the basis functions can be "enriched" to capture discontinuities or sharp gradients in the solution.
This is an application that can also be fetched from https://sourceforge.net/projects/igafem/. It has been hosted in OnWorks in order to be run online in an easiest way from one of our free Operative Systems.
