The Courant-Friedrichs-Lewy Condition by Carlos S. Kubrusly, Carlos A. de Moura,Birkhäuser edition, paperback.

In mathematics, the Courant–Friedrichs–Lewy (CFL) condition is a necessary condition for convergence while solving certain partial differential equations (usually hyperbolic PDEs) arises in the numerical analysis of explicit time integration schemes, when these are used for the numerical solution.

As a consequence, the time step must be less than a certain time in many. Richard Courant (January 8, – Janu ) was a German American mathematician. He is best known by the general public for the book What is Mathematics?, co-written with Herbert Robbins.

$\begingroup$ Thank you. More references would certainly be appreciated. I am trying to solve the following—your post has been very informative since I find making the spatial steps too small using explicit methods results in very large oscillations, while using implicit methods is both computationally intensive and the output appears to not evolve properly (very little change from initial.

Abstract The Courant–Friedrichs–Lewy (CFL) criterion for the stability of numerical schemes is herein investigated at the conservative interface that divides rotating grids embedded within fixed grids.

This issue is of specific interest to correctly assess the power coefficient and the energy production of vertical-axis wind turbines (VAWTs).

Further, the majority of such numerical schemes applied to fluid dynamics ends up having a stability condition dependent on a dimensionless number called the Courant-Friedrichs-Lewy (CFL) number.

The details of each phase are listed in Table 1. The time step size is set to s, which can keep the convergence of the simulations based on the Courant-Friedrichs-Lewy (CFL) criterion [ Under conditions (e.g., Courant-Friedrichs-Lewy conditions) on the size of all location time steps-namely, that they be proportional to the local spatial mesh size - a mesh refinement algorithm cannot be a ''reasonable'' algorithm if, near some space-time surface, the spatial mesh is refined to size o(h/sup 2/), i.e., smaller than order h/sup 2/.

Posted June 27th, by tamys.$\begingroup$ I don't have permissions to add tags yet. Would someone please add a tag for CFL? I recommend "The CFL condition, named for its originators Courant, Friedrichs, and Lewy, requires that the domain of dependence of the PDE must lie within the domain of dependence of the finite difference scheme for each mesh point of an explicit finite difference scheme for a hyperbolic PDE.".
