Energetic BEM-FEM coupling for wave propagation in 3D multidomains.

SUMMARY Starting from a recently developed energetic space-time weak formulation of boundary integral equations for wave propagation problems, a coupling algorithm is presented, which allows a flexible use of FEMs and BEMs as local discretization techniques. Emphasis is given to theoretical and experimental analysis of the stability of the proposed method. Several numerical results on model problems are presented and discussed, showing that both bounded and unbounded three-dimensional domains can be efficiently addressed.
