A non-overlapping TH-domain decomposition
In a previous paper a class of domain decomposition procedures, which may be viewed as a generalization of the Trefftz method, was announced: TH-domain decompositions. Their essential feature is that local solutions are not matched directly, but instead are used as specialized test functions with the property that, when they are applied as weighting functions, the information is concentrated on the internal boundaries of the subdomains. In this manner, the solution on the whole domain is constructed. In this paper such a method, which has already been used in some specific applications, is presented.  1997 Elsevier Science Limited
