Newton-Krylov-Schwarz methods solve nonlinear equations by using Newtons method with a Schwarz domain decomposition preconditioned Krylov method to approximate the Newton step. In this paper we discuss the design and implementation of Newton-Krylov-Schwarz solvers in the context of the implicit temporal integration on an unstructured three-dimensional mesh of the Navier-Stokes evaluations for modeling flow in a river bend.
