Weakly compressed liqiud simulation

• The code is mainly code transplanted from SPlisHSPlasH

• The code use Taichi programming language

Current implement algorithm

• [SESPH]
• [PCISPH]
• [IISPH]
• [DFSPH]

How to run

• First config your anaconda workspace, and open the anaconda prompt
• Second you need install taichi language, pip install taichi
• Last you type ti dfsph.py, that's all

Possion disk sample(full parallel) for boundry handling

Implicit viscosity solver

Use precondition cg to solve viscosity:

Surface tension (without & with):

anistropic mesh restruction :

• marching cube

• using anistropic kernel to build the volume field

• render image

Other algorithm:

• hash grid

• cfl time step
