YADE stops when click [Show 3D] button

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Dear Yade user,

I am using facetBunker (funnel like shape) to rain the particles. It gave me the following problem:

IndexError                                Traceback (most recent call last)
/usr/lib/yade/py/yade/__init__.pyc in <module>()

/usr/lib/yade/py/yade/__init__.pyc in checkUnbalanced()
     51    if utils.unbalancedForce()<.05:
     52       O.pause()
---> 53       plot.saveDataTxt('bbb.txt.bz2')
     54
     55 def addPlotData():

/usr/lib/yade/py/yade/plot.pyc in saveDataTxt(fileName, vars)
    641         else: f=open(fileName,'w')
    642         f.write("# "+"\t\t".join(vars)+"\n")
--> 643         for i in range(len(data[vars[0]])):
    644                 f.write("\t".join([str(data[var][i]) for var in vars])+"\n")
    645         f.close()

IndexError: list index out of range

I can avoid this error by reducing number of particles significantly. Is there anyone can help me what is the IndexError: list index out of range means? and what is the work around so that I can use the funnel but at the same time don't want to reduce the number of particle.

Thank you,
Best Regards,

Alsidqi

Hi Alsidqi,

sorry for late relpy. Could you please attach an example script (just copy
it to the mail body) reproducing the error? If you could delete unnecessary
code, it would be nice :-) With the script we can try to run it and it will
help us to solve the prbolem
Thanks

Dear Jan,

Thanks for help. The following is the code.

from yade import pack, plot
O.bodies.append(utils.geom.facetBox((.5,.5,1),(.5,.5,1),wallMask=29))

O.bodies.append(utils.geom.facetBunker((.5,.5,1.5),1,0.5,4,0.5,hPipe=0.1))

O.bodies.append(utils.geom.facetBox((1.25,0.5,.25),(.25,.25,.25),wallMask=2))
O.bodies.append(utils.geom.facetBox((1.25,0.5,.25),(.25,.25,.25),wallMask=4))
O.bodies.append(utils.geom.facetBox((1.25,0.5,.25),(.25,.25,.25),wallMask=8))
O.bodies.append(utils.geom.facetBox((1.25,0.5,.25),(.25,.25,.25),wallMask=16))
O.bodies.append(utils.geom.facetBox((1.25,0.5,.25),(.25,.25,.25),wallMask=32))

O.bodies.append(facet([(1,0,2),(1,1,2),(1,1,0.5)],dynamic=False))
O.bodies.append(facet([(1,0,2),(1,1,0.5),(1,0,0.5)],dynamic=False))

O.bodies.append(facet([(1,0,0.5),(1,0.25,0.5),(1,0.25,0)],dynamic=False))
O.bodies.append(facet([(1,0,0.5),(1,0.25,0),(1,0,0)],dynamic=False))

O.bodies.append(facet([(1,0.75,0.5),(1,1,0.5),(1,1,0)],dynamic=False))
O.bodies.append(facet([(1,0.75,0.5),(1,1,0),(1,0.75,0)],dynamic=False))

#O.materials.append(FrictMat(density=2e3,young=30e6,poisson=.2,frictionAngle=.6,label="soils"))

sp=pack.SpherePack()
sp.makeCloud((0.15,0.15,2),(0.85,0.85,6.5),rMean=.02)##,rRelFuzz=0.)
sp.toSimulation()

O.engines=[
   ForceResetter(),
   InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
   InteractionLoop(
      [Ig2_Sphere_Sphere_L3Geom(),Ig2_Facet_Sphere_L3Geom()],
      [Ip2_FrictMat_FrictMat_FrictPhys()],
      [Law2_L3Geom_FrictPhys_ElPerfPl()]
   ),
   GravityEngine(gravity=(0,0,-9.81)),
   NewtonIntegrator(damping=0.05),
   PyRunner(command='checkUnbalanced()',realPeriod=2),
   PyRunner(command='addPlotData()',iterPeriod=100)
]

O.dt=.5*utils.PWaveTimeStep()
O.trackEnergy=True

def checkUnbalanced():
   if utils.unbalancedForce()<.05:
      O.pause()
      plot.saveDataTxt('bbb.txt.bz2')

def addPlotData():
   plot.addData(i=O.iter,unbalanced=utils.unbalancedForce(),**O.energy)

yade.qt.View();

#plot.plots={'i':('unbalanced',None,O.energy.keys)}
#plot.plot()
O.saveTmp()

I have one more question:
How I change the properties of the spheres that I already created using makecloud.

Thank you very much,
Best Regards,

Alsidqi

Hi Alsidqi,

sorry for very late answer again. With the script you sent, I have no
problem with graphics. What system do you use and what version of Yade do
you have and how did you install it (from packeges or from source)?

 you can modify properties by:

sp=pack.SpherePack()
sp.makeCloud((0.15,0.15,2),(0.85,0.85,6.5),rMean=.02)##,rRelFuzz=0.)
spheresIDs = sp.toSimulation()
for i in spheresIDs:
  b = O.bodies[i]
  b.state.whatever = whatever # [3], velocity, position...
  b.shape.whatever = whatever # [1,2], radius, color...

cheers
