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
