A parallelizable method for two-dimensional wave propagation using subdomains in time with Multigrid and Waveform Relaxation

In this paper we compare the implicit schemes for the solution of the two-dimensional wave equation using Singlegrid and Multigrid methods. The discretization is performed using the Finite Difference Method, weighted in time by an established parameter. The parallelization of the algorithms is ensur...
