oa Parallel Numerical Simulation of Waves in Dispersive Media

The numerical simulation of waves in bounded dispersive media is accomplished by solving a collection of non-coercive elliptic problems in the space-frequency domain, with absorbing boundary conditions imposed at the artificial boundaries. The computational algorithm is based on a new iterative spatial domain decomposition technique applied to a Galerkin finite element approximation of the governing partial differential equations and is implemented to be portable to several state-of-the-art parallel architectures. Numerical experiments showing the efficiency of the parallel procedure are presented.
