A 3D sparse LBM solver implemented using Taichi
Your code is really useful. Thank you very much for your contribution. I encountered a problem while using the program. I noticed that when using the gridToVTK function to output...
Dear Dr. Yang I want to compare the simulated results with the analytical results for the plane poiseuille flow problem, but the simulated maximum velocity is far from the analytical...
Hello, Professor! I have encountered a problem with the example you provided in img_ftb1131.txt. The file LBM_3D_SinglePhase_Solver.py provides two tau_f.  when I use the `self.tau_f=3.0*self.niu+0.5` The permeability results are...
Hi, I am trying to verify the performance on an A100 PCIe version. However, I can't get the expected performance reported in your paper. Currently I am getting 467 MLUPs...
老师您好~ 我在使用LBM进行批量模拟数字岩心的绝对渗透率时，经常会遇到一个报错 `Traceback (most recent call last): File "/lustre/home/2001110637/LBM/LBM.py", line 1067, in init() File "/lustre/home/2001110637/.conda/envs/test/lib/python3.11/site-packages/taichi/lang/kernel_impl.py", line 1113, in wrapped return primal(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^ File "/lustre/home/2001110637/.conda/envs/test/lib/python3.11/site-packages/taichi/lang/kernel_impl.py", line 1045, in __call__ return...
Dear Dr. Yang, I am very interested in your code on GitHub and appreciate the excellent work you've done. I have a few questions regarding the required working environment: Does...
     Hello, Dr. Yang. I am new to CFD, I am doing two-phase flow displacement, I built a 64^3 model, apply the driving force in the...
Hi, Dr. yang，I build a fracture(width=12px) to valid the poiseuille flow with the condition in your code, the fy = 1e-4 and niu = 1/6 . The result suggest that...
