Instead of that I see fence-like curves with "top edges" exactly at the positions of cell edges (or exactly in the middle between them). That works even if I don't use any external flow. After I changed the agrid parameter from 1.0 to 2.0 it seemed to disappear. If I do exactly the same simulation with langevin thermostat, I see a flat surface without any "hills" on that. I am just wondering if someone knows why it happens? Thank you in advance!
See the plot examples and a simple code attached.
Actually, there is another question I should ask - what is going to happen if I simulate the particles inside the channel and the boundaries for fluid and particles are not exactly at the same place? Say, lbboundary is 0.5*agrid further from the particles, than md-constraint or vice versa? Thank you!
