Question: Advection in LBM_Taichi and Diffusion in D2Q9

Open wyq977 opened this issue 4 years ago • 0 comments

  1. 想问一下advection在LBM是怎么实现的， 有点看不懂， 是这两行嘛

https://github.com/hietwll/LBM_Taichi/blob/b2d758a5d14ebcf3a59ad0b11b12bcbfd1c11187/lbm_solver.py#L77 https://github.com/hietwll/LBM_Taichi/blob/b2d758a5d14ebcf3a59ad0b11b12bcbfd1c11187/lbm_solver.py#L77

  1. 想问下为什么我试着diffusion 结果不是很理想，感觉边界的rho(density) 很奇怪

中间正方形

谢谢🙏
