Question #268691 on Yade changed:
https://answers.launchpad.net/yade/+question/268691
Description changed to:
Hi guys!
I try to study the displacement of various spheres ( with different
weight ) when they apply the same force, on a surface which previously
has been created and is composed of other spheres.
My problem is the IterPeriod of the PyRunner function that I create for
apply the force on the sphere that I want, in this case, green spheres.
If I put the period = 1 , the force is constantly applied .How I can apply the
force only once? PyRunner(command='force()',
¿?¿?¿?iterPeriod=¿?¿?¿,initRun=True,label='checker'),
My first choice was to put a high period (1 for example), but
this way , the green sphere falls on the surface of spheres before the
force was applied . What I need is to apply a force on green particle
when it is "in the air " to describe a parabolic movement to fall on the
surface and stop.
The second PyRunner is to store the position data ( x , y, z) and the
green particle velocity .
Thanks in advance =)

Hi guys!
I try to study the displacement of various spheres ( with different
weight ) when they apply the same force, on a surface which previously
has been created and is composed of other spheres.
My problem is the IterPeriod of the PyRunner function that I create for
apply the force on the sphere that I want, in this case, green spheres.
If I put the period = 1 , the force is constantly applied .How I can apply the
force only once? PyRunner(command='force()',
¿?¿?¿?iterPeriod=¿?¿?¿,initRun=True,label='checker'),
My first choice was to put a high period (1 for example), but
this way , the green sphere falls on the surface of spheres before the
force is applied . What I need is to apply a force on green particle
when it is "in the air " to describe a parabolic movement to fall on the
surface and stop.
The second PyRunner is to store the position data ( x , y, z) and the
green particle velocity .
Thanks in advance =)
