I am not sure if it works. You can try to put your system into two frozen layers which will exert a resisting force on the wall. You still need to put an acceleration on the wall. But after a steady state is reached, you will see the wall will move approximately at a constant velocity.

Is there any possibility to define a constant velocity of my rigid wall, not an acceleration? >Vitaly >>Hi, have you set comm-mode = None? If no, you can set it and try again.
