Abstract

In this chapter, we present the theoretical background and discuss the numerical performance of CAD-macroelements in which the solution is approximated with B-splines. Univariate as well as two-dimensional tensor-product interpolation will be considered. Not only the usual Curry–Schoenberg B-splines normalized to provide a partition of unity, but also “reduced cardinal B-splines” are studied (to fully explain some older papers of the CAD/CAE group at NTUA since 1989). Numerical experiments of this chapter restrict to the Galerkin–Ritz formulation and refer to domains or structures of simple 2D primitive shapes (rectangles, circles, and ellipses). The numerical analysis is performed using a single macroelement only, without domain decomposition. The results are also compared with the FEM solution of the same mesh density.
