Abstract
In this chapter we describe an accurate, efficient and robust technique to solve the steady
Euler equations for inviscid flow by a nonlinear multigrid method. The discretization is a finite
volume one, using the Godunov scheme, with Osher's approximate Riemann solver as the numerical
flux function. Nonlinear FAS multigrid cycling is used to directly solve the first-order discrete
equations. Defect correction is used to obtain higher-order accuracy. The technique can be
extended to the N avier-Stokes equations, and can be combined with the adaptive grid refinements.
