A seamless communication of computer aided design (CAD) and computer aided engineering (CAE) has always been the ultimate goal in product lifecycle management. The forward in- tegration CAD/CAE, in which the simulation tasks are operated directly on CAD model, can be achieved by the isogeometric analysis (IGA) within the conventional finite element method (FEM). Despite of this successful implementation that covers many engineering aspects, the crucial challenge in this CAD/CAE integration is the incompatible geometric representation, namely the volumetric representation of CAE versus the boundary representation of CAD in three-dimensional problems.

In this project, we developed a symmetric Galerkin boundary element method (SGBEM) based on non-uniform rational B-splines (NURBS) for three-dimensional problems in linear elasto-statics. It exploits the common boundary representation of isogeometric analysis (IGA) and boundary element method (BEM).
