TVD remeshing formulas for particle methods
We derive TVD remeshing formulas for particle methods. The derivation is inspired from a finite-difference analysis but the method retains the essential features of particle methods. Numerical illustrations give evidence of the improved stability and computational cost resulting from these new algorithms. Résumé Schémas de remaillage TDV en méthodes particulaires. On décrit dans cette note des ...
متن کاملAccurate, non-oscillatory, remeshing schemes for particle methods
In this article we propose and validate new remeshing schemes for the simulation of transport equations by particle methods. Particle remeshing is a common way to control the regularity of the particle distribution which is necessary to guarantee the accuracy of particle methods in presence of strong strain in a flow. Using a grid-based analysis, we derive remeshing schemes that can be used in ...

15 صفحه اولEntropy Consistent, Tvd Methods with High Accuracy for Conservation Laws
The Godunov method for conservation laws produces numerical solutions that are total-variation diminishing (TVD) and converge to weak solutions which satisfy the entropy condition (Entropy Consistency), but the method is only first order accurate. Many second and higher order accurate Godunov–type methods have been developed by various researchers. Although these high order methods perform very...
متن کاملConsistency, accuracy and entropic behaviour of remeshed particle methods
In this paper we analyse the consistency, the accuracy and some entropy properties of particle methods with remeshing in the case of a scalar one-dimensional conservation law. As in [7] we re-write particle methods with remeshing in the finite-difference formalism. This allow us to prove the consistency of these methods, and accuracy properties related to the accuracy of interpolation kernels. ...
