Hi,
I have a geometry like the attached and I'd like to move the empty box forward and back, I use a dynamic mesh with layering technique.
I thought to write a profile in this way:

((x_motion 2 point)
(time 0.001 0.002 )
(v_x 0.05 -0.05)

and then to use a timestep of 0.001 and 200 number of time step in order to see the preview of my dynamic mesh but my empty space moves only forward.

So I tried with this:

((x_motion transient 2 0)
(time 0.001 0.002)
(v_x 0.05 -0.05)

and it didn't work too (same problem, it moves only forward).

Someone knows how I can solve my problem?

Thank you!
