An Augmented Lagrangian Preconditioner for Navier--Stokes Equations with Runge--Kutta in Time

Santolo Leveque, Yunhui He, Maxim Olshanskii

We consider a Runge--Kutta method for the numerical time integration of the nonstationary incompressible Navier--Stokes equations. This yields a sequence of nonlinear problems to b…
