Hi, Jan
Thanks for your answer.

###
stress = 1e7 # max stress, Pa
rate = 1e8 # stress rate, Pa/s
def applyForce():
    f = O.time * rate # linear increase, can be whatever else
    f = min(f,stress) # not to excess max stress
    O.forces.setPermF(Boxid,(0,0,f))

O.engines = [
    ...
    PyRunner(iterPeriod=1,command="applyForce()"),
]

> stress = 1e7 # max stress, Pa
Here what we apply is 'stress(Pa)' rather than 'force(N)'?
