Hi
I'm modeling a system with channel flow in the x direction.
The bottom wall of the channel vibrates to induce acoustic waves in the y direction.
Is it possible in LAMMPS to simulate movement of the boundary (similar to a moving mesh in CFD packages)?
I had considered rebuilding the boundary at every time step, but 1. I am not sure how to avoid losing free particles when a boundary is moved this ways and 2. hoped a more elegant, computationally cheap solution is part of the existing package.
Best regards,
Ro'ee

how about using fix move?
