把第二行改成1 1.0 意思是使用固定颜色边界，边界上的颜色固定为1.0 renxiaosa00 ***@***.***> 于 2023年10月25日周三 上午8:03写道： > 我的颜色边界采用的默认的代码： > bc_psi_x_left, psi_x_left = 1, -1.0 > bc_psi_x_right, psi_x_right = 0, 1.0 > bc_psi_y_left, psi_y_left = 0, 1.0 > bc_psi_y_right,...

颜色LBM 使用phi 来表示non-wetting phase 或者wetting phase, phi的值一般介于-1.0 到 1.0 之间，我们一般可以简单的认为小于零的就是non-wetting phase, 大于0的是wetting phase (也和接触角有关，接触角变了也可能这两个反过来)。我那里写的-1.0 = phase 1 意思就是-1.0 表示non wetting phase, 1.0 = phase 2 意思是1.0 表示phase 2 (wetting phase)....

This is due to the use of periodic on the right hand side. Because the right BC's neighbour becomes the left BC which is a fixed color... So you can...

The second line of phase boundary you need to use 1 1.0 not 1 -1.0, 1.0 represent red phase, -1.0 represents blue phase On Thu, 25 Jan 2024 at 12:18,...

Maybe you need bigger driving force, I would suggest using periodic and body force to drive the fluid instead of using fix velocity/pressure BC On Thu, 25 Jan 2024 at...

You want to inject fluid from three inlets? It's not an easy case for bodyforce, I think you can only use velocity BC for three inlets and constant pressure BC...

Maybe you need to change bc_x_right into 1, 0.99, 0.0, 0.0 ,0.0 ? On Thu, 25 Jan 2024 at 23:34, emwn123 ***@***.***> wrote: > Hi Dr. Yang, > > Sorry...

Hi Xiangwu, thanks for your help on identifying the bug. To calculate permeability is not difficult, it is based on darcy's law, as we are working on a discrete space,...

Hi XiangWu, I think there are several things you can check, first of all, v is an "array" of dimension of 4, so if you want to show the min...
