Abstract

In this paper, we are concerned with a kind of Signorinitransmission problem in a unbounded domain. A variationalinequality is derived when discretizing this problem by coupledFEM-BEM. To solve such variational inequality, an iterativemethod, which can be viewed as a variant of the D-N alternativemethod, will be introduced. In the iterative method, the finiteelement part and the boundary element part can be solvedindependently. It will be shown that the convergence speed of thisiteration is independent of the mesh size. Besides, a combinationbetween this method and the steepest descent method is alsodiscussed.
