Convergence Acceleration of High Order Numerical Simulations using a Hybrid Spectral Dierence - Finite

The goal of this paper is to show how numerical simulations of uid ow using high order methods for unstructured meshes can be sped up using a hybrid multigrid method. In our work we accelerate the steady state convergence of a Spectral Dierence code by coupling it to a Finite Volume solver. While we want to obtain the solution for the SD code, low frequency corrections to the solution are computed using the nite volume code.
