Abstract
This paper presents an isogeometric boundary element method (IGABEM) for transient heat conduction analysis.
The Non-Uniform Rational B-spline (NURBS) basis functions, which are used to construct the geometry of the
structures, are employed to discretize the physical unknowns in the boundary integral formulations of the governing equations. B´ezier extraction technique is employed to accelerate the evaluation of NURBS basis functions. We
adopt a radial integration method to address the additional domain integrals. The numerical examples demonstrate
the advantage of IGABEM in dimension reduction and the seamless connection between CAD and numerical
analysis.
