Direct numerical simulation of turbulence at lower costs [PDF]
, 1995 Direct Numerical Simulation (DNS) is the most accurate, but also the most expensive, way of computing turbulent flow. To cut the costs of DNS we consider a family of second-order, explicit one-leg time-integration methods and look for the method with the

On Local Relaxation Methods and Their Application to Convection-Diffusion Equations [PDF]
, 1981 This paper discusses local relaxation (LR) methods which can be regarded as generalizations of the successive overrelaxation (SOR) method. The difference is that within an LR method the relaxation factor is allowed to vary from equation to equation.

Numerical methods for Hamilton–Jacobi type equations [PDF]
, 2016 We give an overview of numerical methods for first-order Hamilton–Jacobi equations. After a short presentation of the theory of viscosity solutions, we show their link with entropy solutions of conservation laws.
