Next: Algorithm for the discretised Up: Crack problems for three-dimensional Previous: FM-GBIEM


In FM-GBIEM we shall use a modified version of the original FMM by Greengard[33], the outline of which will be included here in order to explain how the tools prepared so far can be incorporated into the FMM algorithm (See Greengard[33] for further details). We note that this algorithm will be used not only in solving the variational boundary integral equation in (3.100), but also in the computation of quantities such as stresses and displacements in the interior of the domain D.
