Comparative study on accuracy and conservation properties of two particle regularization schemes and proposal of an optimized particle shifting scheme in ISPH context
Accuracy and conservation properties of two particle regularization schemes are comparatively investigated. The considered particle regularization schemes are dynamic stabilization and particle shifting. An optimized particle shifting is proposed for free-surface flows. The optimized particle shifting is free of tuning parameters and eliminates shifting normal to an interface. The optimized particle shifting outperforms dynamic stabilization in terms of accuracy and energy conservation.
