On the Implementation of a Fully Discrete
Multiscale Galerkin, Angewandte Mathematik · 1997
We present a boundary element method on general polyhedral surfaces in space. The shape functions are piecewise constant multiwavelets. The N x N stiffness matrix is numerically sparse, i.e. only O(7V(log 7V)^) entries with a-priori known locations need to be computed. Numerical results for > 10^ unknowns are presented.
