✦ Synopsis

The interaction of acoustic waves with submerged structures remains one of the most di cult and challenging problems in underwater acoustics. Many techniques such as coupled Boundary Element (BE)=Finite Element (FE) or coupled InΓΏnite Element (IE)=Finite Element approximations have evolved. In the present work, we focus on the steady-state formulation only, and study a general coupled hp-adaptive BE=FE method. A particular emphasis is placed on an a posteriori error estimation for the viscoelastic scattering problems. The highlights of the proposed methodology are as follows

An iterative procedure is described for the finite-element solution of scalar scattering problems in unbounded domains. The scattering objects may have multiple connectivity, may be of different materials or with different boundary conditions. A fictitious boundary enclosing all the objects involved

A general approach to impose homogeneous boundary conditions on algebraic systems deriving from variational formulations of di!erential problems is presented. The proposed approach proves to be e!ective and its performances are particularly enhanced when sparse matrices are dealt with. It applies to
