The multiblock method. A new strategy based on domain decomposition for the solution of wave propagation problems

A novel single-step domain decomposition technique for the elastic wave propagation problem is introduced in this paper, based on the Huygens principle. The method allows an e ective and e cient implementation on parallel computers through coarse-grain multiprocessor computations. The various tests and numerical examples let infer that it is very competitive in comparison with classic substructuring techniques, specially for implicit discretization schemes.
