Dear all,
At first: I am beginner in YADE.
I have simulated clumps spherical particles.
I have modeled 3000 particles, I mean I have 3000 clumps.
I want to get as output (text or excel): If particles in specified range of my
volume are moved, printing their positions continuous.
Because of having too many particles and then positions, I want to have just
position of moved particles.
How I can get this aim?
I wrote this code: but I do not know how write code for : if particles moved
.....
def positions():
for b in O.bodies:
if b.state.pos[0]>(2.9) and b.state.pos[0]<7 and b.state.pos[1]>4 and
b.state.pos[1]<19: # flow zone
iter0=O.iter
Positions=open("Positions clumpId iter x y.txt","a")
Positions.write(repr(clumpId)+' '+repr(iter0)+'
'+repr(b.state.pos[0])+' '+repr(b.state.pos[1])+' '"\n")
Positions.close()
O.engines=O.engines+[PyRunner(command='positions()',iterPeriod=300000,label="flow")]
And can I use for this purpose with this code: if yes how to use and write?
class yade.wrapper.StepDisplacer((object)arg1)
Many thanks for your help.
