Hi, all.
Now I'm trying to use the cluster to do some simulation work. But there seem
some errors.
Actually, the cluster can run for one of my scripts, but when I add another two
line codes, this cluster can't work. There will be an error pop up.
here is my script:
from yade import pack, plot
from yade import utils
compFricDegree = 30
targetPorosity = 0.98
stabilityThreshold=0.3
finalFricDegree=19.5
damp=0.8
young=4e8
O.materials.append(CohFrictMat(young=young,poisson=0.3,frictionAngle=radians(compFricDegree),isCohesive=False,alphaKr=0.2,alphaKtw=0,etaRoll=0.5,momentRotationLaw=True,density=2648,label='spheres'))
O.materials.append(FrictMat(young=young,poisson=0.3,frictionAngle=0,density=0,label='walls'))
mn,mx=Vector3(0,0,0),Vector3(400e-3,400e-3,300e-3)
psdSizes,psdCumm =
[3e-3,3.48e-3,3.98e-3,4.41e-3,4.78e-3,5.12e-3,5.53e-3,6.09e-3,7.37e-3,9.47e-3],[0.,0.11,0.22,0.33,0.44,0.56,0.67,0.78,0.89,1.0]
sp = pack.SpherePack()
sp.makeCloud(mn,mx,psdSizes=psdSizes,psdCumm=psdCumm,num=50026,distributeMass=1,seed=1)
pred=pack.inCylinder((200e-3,200e-3,0),(200e-3,200e-3,300e-3),radius=200e-3)
sp2 = pack.filterSpherePack(pred,sp,returnSpherePack=True)
sp2.toSimulation(material='spheres')
facets =
geom.facetCylinder((200e-3,200e-3,150e-3),200e-3,300e-3,wallMask=6,material='walls',segmentsNumber=100)
O.bodies.append(facets)
print "num_spheres= ", len(O.bodies)
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom6D(),Ig2_Facet_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys(),Ip2_CohFrictMat_CohFrictMat_CohFrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack(),Law2_ScGeom6D_CohFrictPhys_CohesionMoment(useIncrementalForm=True,always_use_moment_law=True,label='cohesiveLaw')]
),
GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=10,timestepSafetyCoefficient=0.8),
NewtonIntegrator(gravity=(0,0,-9.81),damping=damp),
]
O.dt=.5*PWaveTimeStep()
while 1:
O.run(3000,True)
unb=unbalancedForce()
print 'unbalanced force: ',unb
if unb<stabilityThreshold:
break
O.save('make_sample_1.yade.gz')
O.saveTmp()
#####################
if I didn't include these two lines:
#pred=pack.inCylinder((200e-3,200e-3,0),(200e-3,200e-3,300e-3),radius=200e-3)
#sp2 = pack.filterSpherePack(pred,sp,returnSpherePack=True)
and change :sp2.toSimulation(material='spheres') to
sp.toSimulation(material='spheres')
the cluster can run this script.
if I run the script that I posted. Here is the error:

Is there anyone can help me to figure out the reason why I just add that two
line codes, this script can't work.
