In this contribution we extend our work on the application of boundary integral equations to accurately predict the shielding properties of complex enclosure geometries. The focus of this contribution is on the power of the splay tree algorithm to efficiently extract symmetry properties from a geometry. We will show that by using these splay trees in two as well as three dimensions significant savings in CPU time can be achieved allowing for the evaluation of ever more complex structures within a given computation time. We show different results for enclosures in two dimensions and also illustrate the time savings of splay trees in three dimensions. At the time of the conference we will also show three-dimensional shielding problems.
