A cure for the sonic point glitch [PDF]

, 2000
Among the various numerical schemes developed since the '80s for the computation of the compressible Euler equations, the vast majority produce in certain cases spurious pressure glitches at sonic points.

A higher order numerical method for transonic flows [PDF]

, 1997
This thesis presents and verifies a numerical method for solving the compressible Euler equations. The method is based on a finite volume method with an upwind type TVD dissipation terms originally developed by Harten ( 1983 ) for scalar hyperbolic ...

Finite Difference formulation of any lattice Boltzmann scheme

, 2022
International audienceLattice Boltzmann schemes rely on the enlargement of the size of the target problem in order to solve PDEs in a highly parallelizable and efficient kinetic-like fashion, split into a collision and a stream phase.

Nonuniqueness of lattice Boltzmann schemes derived from finite difference methods

Examples and Counterexamples
Recently, the construction of finite difference schemes from lattice Boltzmann schemes has been rigorously analyzed [Bellotti et al. (2022), Numer. Math. 152, pp. 1–40].
