Hi everyone, 

I recently installed Yade version 2019-07022.git-585c6c1 on a Ubuntu 18.04 machine. I have an old script that used to run with yade 1.07.0 correctly, I have replaced O.forces.addF(upper_wall.id, (0,-force,0), permanent = True) with O.forces.setPermF(upper_wall.id, (0,-force,0)), but the wall position doesn't change during the simulation.  I also tried to use the old code addF, other than getting the warning: method deprecated, the wall position still doesn't change.

Here's a code snippet:

bottom_wall = O.bodies[wall[2]]
bottom_wall.state.blockedDOFs = 'xzXYZ'
bottom_wall.state.mass = 1

upper_wall = O.bodies[wall[3]]
upper_wall.state.blockedDOFs = 'xzXYZ'
upper_wall.state.mass = 1

#set force
app_stress = range(2,26,2)
index = 0
force = app_stress[index]*1e6*0.02*0.02
O.forces.setPermF(upper_wall.id, (0,-force,0))
O.forces.setPermF(bottom_wall.id, (0,force,0))


Does anyone know what's causing this issue? 


Thank you.
