Jan Stránský proposed the following answer:
Hi​,
thanks for the files. I have no problem with the script, the facets moves
exactly as prescribed. You can check it by defining following function and
calling it in O.engines with PyRunner:

################
def printVel():
  b = O.bodies[upper_platen[0]]
  vel = b.state.vel
  pos = b.state.pos
  print vel,pos
O.engines = [
   ...
   PyRunner(iterPeriod=1,command='printVel()'),
]
################

Of course, because of the velocity (~1e-1) and time step(~4e-8), the motion
is not visible, but it is a different story..

cheers
Jan
