Abstract

The sample point error analysis and related adaptive boundary element refinement, proposed by one of the present authors, is extended to the problem with subregion partition which is often required for maintaining higher accuracy and for treatment of composite dissimilar materials. The present study is devoted to regularization of the requirement that the interface between neighboring subregions should be discretized by the unified criterion for the both, while, in general, the error influences on the point on the interface from one region differs from that from the other. Two examples concerning the two-dimensional Laplace equation are tested to verify the availability of the proposed method.
