Abstract

This paper presents how to track the surface of a multiphase fluid more accurately by using the particle level set method with anisotropic instead of spherical particles. While we use the weighted version of principal component analysis (WPCA) to construct the anisotropic particles, its computational cost is high. We adopt the distribution of particles from the directional derivative to generate the anisotropic particles. Compared to particle level set method, our approach provides more details of surface, corrects numerical dissipation, and preserves the volume of the fluid. Furthermore, we present particle-based fluid simulations with surface reconstruction that uses anisotropic particles.
