Christian Jakob proposed the following answer:
in your script i see some inconsistencies, that can lead to unexpected
results:
##### 1. problem:
idSand=O.materials.append(FrictMat(young=young,poisson=pr,frictionAngle=radians(fa),label='idSand'))
#frictionAngle=fa !!!
##### 2. problem:
O.bodies.append(geom.facetBox((0.035,0.035,0.035),(0.035,0.035,0.035),wallMask=15,
material = BoundaryMat, dynamic=1))
#this is ok
O.bodies.append(geom.facetBox((0.035,0.035,0.035),(0.035,0.035,0.035),wallMask=15,
dynamic=1))
#missing material = BoundaryMat !!!
O.bodies.append(utils.geom.facetBox((0.035,0.035,0.035),(0.035,0.035,0.035),wallMask=16,dynamic=0))
#missing material = BoundaryMat !!!
O.bodies.append(utils.geom.facetBox((0.035,0.035,0.105),(0.035,0.035,0.035),wallMask=15))
#missing material = BoundaryMat
##### 3.problem:
sp=pack.SpherePack()
sp.makeCloud(mincorner,maxcorner,psdSizes=psdSizes,num=number,psdCumm=psdCumm,distributeMass=1)
sp.toSimulation()
you did not set material for spheres. but i do not know how to do this with
sp.toSimulation()
i prefer to use:
O.bodies.append([sphere(c,r,material=idSand) for c,r in sp])
#instead of sp.toSimulation()
regards,
christian
