PIC & FLIP fluid simulation

This is the code of the final project for the course Physically-Based Simulation in Computer Graphics, ETHZ, HS2021. We use Taichi to implement a fluid solver as described in the paper: Zhu, Yongning and Bridson, Robert, Animating sand as a fluid. ACM Transactions on Graphics 2005, 24, pp. 965-972.
