Abstract Numerical analysis of unsteady heat transfer problems with complex
geometries by the isogeometric boundary element method (IGABEM) is presented. The
IGABEM possesses many desirable merits and features, for instance, (a) exactly
represented arbitrarily complex geometries, and higher-order continuity due to nonuniform rational B-splines (NURBS) shape functions; (b) using NURBS for both field
approximation and geometric description; (c) directly utilizing geometry data from
computer-aided design (CAD); and (d) only boundary discretization. The formulation of
IGABEM for unsteady heat transfer is derived. The domain discretization in terms of
IGABEM for unsteady heat transfer is required as that More >
