FLIP fluid simulation with MGPCG solver in unity
Warning: it was only tested on my RTX4070 graphics card with wave size 32
A Incompressible inviscid Flow using FLIP written in HLSL
4M particles on 256x128x128 grid, simulated on GPU
The grid is solved with a UAAMGPCG solver, but only one iteration
Implemented the algorithm from the paper A Fast Unsmoothed Aggregation Algebraic Multigrid Framework for the Large-Scale Simulation of Incompressible Flow https://computationalsciences.org/publications/shao-2022-multigrid/shao-2022-multigrid.pdf as a preconditioner for the conjugate gradient method
fast rendering with fake reflection using mesh from marching cubes
Implemented the algorithm from the paper Narrow Band FLIP for Liquid Simulations https://www.cs.cit.tum.de/fileadmin/w00cfj/cg/Research/Publications/2016/NBFlip/nbflip.pdf
2D FLIP using Unity Jobs system. and some legacy test code
