A NUMERICAL STUDY OF ENERGETIC BEM-FEM APPLIED TO WAVE PROPAGATION IN 2D MULTIDOMAINSA. Aimi, L. Desiderio, M. Diligenti, and C. GuardasoniDepartment of Mathematics and Computer Science, University of Parma, Parma, Italy; POEMS (UMR 7231, CNRS-ENSTA-INRIA), ENSTA, Paris, France;Abstract: Starting from a recently developed energetic space-time weak formulation of boundary integral equations related to wave propagation problems defined on single and multidomains, a coupling algorithm is presented, which allows a flexible use of finite and boundary element methods as local discretization techniques, in order to efficiently treat unbounded multilayered media. Partial differential equations associated to boundary integral equations will be weakly reformulated by the energetic approach and a particular emphasis will be given to theoretical and experimental analysis of the stability of the proposed method.
