Abstract
The isogeometric boundary element technique (IGABEM) is presented in this study for steady-state inhomogeneous heat conduction analysis. The physical unknowns in the boundary integral formulations of the governing
equations are discretized using non-uniform rational B-spline (NURBS) basis functions, which are utilized to
build the geometry of the structures. To speed up the assessment of NURBS basis functions, the B´ezier extraction
approach is used. To solve the extra domain integrals, we use a radial integration approach. The numerical examples
show the potential of IGABEM for dimension reduction and smooth integration of CAD and numerical analysis.
