Solution Strategies for Integration of Semi-Discretized Flow Equations in elsA and CEDRE

This paper is devoted to the presention of a selection of time integration methods used in the Onera elsA and Cedre software dedicated to the resolution of the compressible Navier-Stokes equations. The selected methods are given in the framework of steady and unsteady flow simulations. Emphasis is put on methods for the resolution of algebraic systems associated with time integration methods for space-discretized equations.
