AB - 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 BĀ“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.
