Question #689821 on Yade changed:
https://answers.launchpad.net/yade/+question/689821

Summary changed to:
Any way to make my code run Faster

Description changed to:
first question :

i try to run my code but i got a little bit problem that i's very slow

Do you have any way to make it run faster
 

this is my code :

 from yade import pack
import matplotlib.pyplot as plt

idSteel=O.materials.append(FrictMat(young=210e9,poisson=.25,frictionAngle=.8,label="steel"))

O.materials.append(FrictMat(young=3e9,poisson=0.3,frictionAngle=radians(30),density=2600,label='spheres'))

cx,cy,cz = 6.3,6.3,6.3 # center of the box
dx,dy,dz = 7.5,7.5,7.5 # half-dimensions of the box
t = 0.25 # half-thickness of walls
left = box((cx-dx-t+1.2,cy+1.2,cz),(t,dy+2*t,cz),fixed=True,wire=True,material="steel")
right = box((cx+dx+t+1.2,cy+1.2,cz),(t,dy+2*t,cz),fixed=True,wire=True,material="steel")
front = box((cx+1.2,cy-dy-t+1.2,cz),(dx,t,cz),fixed=True,wire=True,material="steel")

bottom = box((cx+1.2,cy+1.2,cz-dz-t+1.2),(dx+2*t,dy+2*t,t),fixed=True,wire=True,material="steel")

left2 = box((cx-dx-t+1.2,cy+1.2,cz*2+2.7),(t,dy+2*t,2.7),fixed=True,wire=True,material="steel")
