[Schémas de remaillage TDV en méthodes particulaires]
On décrit dans cette Note des techniques de remaillage TVD pour les méthodes particulaires, en s'insipirant de la méthodologie des schémas de différences finies. Des exemples numériques montrent les gains obtenus par ces nouveaux algorithmes tant en stabilité qu'en coût de calcul.
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.
