Introduction

This program solves an advection-diffusion problem using a geometric multigrid -preconditioner. The basics of this preconditioner are discussed in step-16; +(GMG) preconditioner. The basics of this preconditioner are discussed in step-16; here we discuss the necessary changes needed for a non-symmetric PDE. Additionally, we introduce the idea of block smoothing (as compared to point smoothing in step-16), and examine the effects of DoF renumbering for
