Parallel-in-time Multiscale Algorithm for Wave Equations

Hieu Nguyen, Research Assistant, ICES, University of Texas at Austin

Abstract

We propose a new general framework for building multiscale time-domain decomposition methods. The framework is inspired by the “parareal schemes” introduced by Lions, Maday and Turinici for parallel-in-time computation of evolutionary problems. In this talk, we shall describe our new framework which relies on computed data to build, on-the-fly, effective propagator. We will demonstrate the algorithms that we developed for solving second order wave equations.
