Abstract

In this work one aims to present an efficient algorithm for coupling a generic number of subregions discretized with boundary elements. The followed strategy does not base on condensing the field variables into certain variable blocks, as e.g. the interface variable ones, but instead considers directly the resulting sparse matrix of the coupled system. The main idea of the algorithm is that by using reliable iterative solvers it is then possible to develop multi-zone algorithms without condensing techniques such that, independently of the numbering scheme adopted, only the block matrices with non-zero coefficients are stored and manipulated during the analysis process and, furthermore, the CPU t
