See answer #1
>> To make the box step, just assign it zero velocity:
>> top.state.vel = Vector3.Zero
> I want compaction ... at ... stage which volume equal to 1.0*1.0*1.0.
How to do it ?
use e.g. PyRunner:
###
O.engines = [
...
PyRunner(iterPeriod=1,command="stopBoxIfCompacted()")
]
def stopBoxIfCompacted():
area = ...
height = ...
volume = area * height
if volume < 1.0*1.0*1.0:
top.state.vel = Vector3.Zero
O.pause() # ?
###
cheers
