Description changed to:
Hi,
I am trying to simulate the rotation of a cylinder.
I use
SpherePack() to creat a cylinder
RotationEngine to rotate this cylinder
but the animation shows there is no rotation at all.
What should i do? Thank you for your any suggestions.
Here is the some paragraph of my code——
pred = pack.inCylinder((-groundLength/2,0,0),(groundLength/2,0,0),cylRd)
sp1=SpherePack()
sp1 =
pack.randomDensePack(pred,spheresInCell=2000,radius=.02,returnSpherePack=True)
spheres=sp1.toSimulation(color=(0,1,1),material=concMat)
cylIds=spheres
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Box_Aabb(),]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Box_Sphere_ScGeom6D()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()],
),
RotationEngine(rotateAroundZero=True,zeroPoint=(0,0,0),rotationAxis=(1,0,0),angularVelocity=30*(2*pi/60),ids=cylIds,label='rotor'),
NewtonIntegrator(damping=.3,gravity=(0,0,-1e4)), # gravity artificially
high, to make it faster going ;-)
