Robust and isotropic discretization is applied to guarantee the stability and accuracy.
- •
Successfully repeats the established finite element solutions for high density ratios.
- •
Higher GPGPU performance as compared to phase-field models.
- •
Brute-force reinitialization is computationally superior to PDE-based methods when coupled with LBM.
