Transient dynamic analysis of dam-reservoir interaction by coupling DRBEM and FEM

In this paper, time domain dynamic analysis of dam-reservoir interaction is presented by coupling the dual reciprocity boundary element method in the infinite fluid domain and the finite element method in the solid domain. An efficient coupling procedure is formulated by using sub-structuring method. Sammerfeld's boundary condition for far end of the infinite domain is implemented. To verify the proposed scheme, numerical examples are carried out to compare with the available exact solutions and results of the finite-finite element coupling.
