[Yade-users] [Question #371126]: particles fly out of boundary

[Weimin Song]

New question #371126 on Yade:
https://answers.launchpad.net/yade/+question/371126

Dear all,
  
  I am packing some particles in one cylinder using  randomDensePack  
and append one wall upwards. Why did the particles fly out of the boundary?  
  
  BTW, warning information exists after the randomDensePack:

No suitable packing in database found, running PERIODIC compression
/home/vigoss/myYade/install/lib/x86_64-linux-gnu/yade-Unknown/py/yade/pack.py:296:
 FutureWarning: The default behavior will change; specify returnSpherePack=True 
for the new behavior, and False to get rid of this warning (your code will 
break in the future, however). The returned SpherePack object can be added to 
the simulation using SpherePack.toSimulation()
  warnings.warn('The default behavior will change; specify 
returnSpherePack=True for the new behavior, and False to get rid of this 
warning (your code will break in the future, however). The returned SpherePack 
object can be added to the simulation using 
SpherePack.toSimulation()',category=FutureWarning)


from yade import pack

O.bodies.append(wall((0,0,0.01), axis=2, sense=-1, color=(0,0,1), mask=1))

O.bodies.append(geom.facetCylinder(center=(0,0,0), radius=0.005, height=0.02, 
orientation=Quaternion((0, 0, 1), 0), segmentsNumber=100, wallMask=6, 
angleRange=None, closeGap=False, radiusTopInner=-1, radiusBottomInner=-1))
pred=pack.inCylinder(centerBottom=(0,0,-0.01),centerTop=(0,0,0.01),radius=0.005)

O.materials.append(FrictMat(young=30e9,poisson=.3,frictionAngle=.5))

spheres=pack.randomDensePack(pred,radius=0.0008,color=None,rRelFuzz=0.5, 
spheresInCell=400,memoDbg=False,memoizeDb=None)

O.bodies.append(spheres)

Hi Mike,
currently YADE does not support MPI (distributed memory) parallelization.
However, you can still use shared memory parallelization even on server
(limited to one computer).

Hi again,

Following your guidance, I'm ok to run YADE on my computer (with 7
cores) (Open MP). Is that ok for running YADE in server (I mean run YADE
in MPI)?

Thank you for your help.
