    Abstract

    We design and analyze a Schwarz waveform relaxation algorithm for domain
    decomposition of advection-diffusion-reaction problems with strong
    heterogeneities. The interfaces are curved, and we use optimized Robin or
    Ventcell transmission conditions. We analyze the semi-discretization in time
    with Discontinuous Galerkin as well. We also show two-dimensional numerical
    results using generalized mortar finite elements in space.
