I am facing a similar problem with the parameters grid size, friction, mass and viscosity. And I still don't understand how these parameters correlate.
Right now I am experimenting with a single point with external force (gravitation) and its final velocity in the fluid.
A line got my attention in the userguide, maybe there is the problem/solution:
"Internally the LB implementation works with a different set of units: all lengths are
expressed in agrid , all times in tau and so on. Therefore changing agrid and tau, might
change the behaviour of the LB fluid"
And it certainly changes the behaviour!

I realized I didn’t attach a simulation script to my question, so I’m attaching it now. Please, let me know what could be the issue. Thank you, Iva
