Hello,
I am trying to simulate a rotating drum. To avoid the effect of the front and
back wall of the drum, instead of choosing the length of the drum very long I
want to set periodic boundary only in this direction(z direction). So I defined
a box with the same dimension of the drum in the z direction, and bigger than
the radius of the drum. The drum center is located on (0,0,0) with the radius
0.5m and length of 0.2. So I defined the box as :
sp=pack.SpherePack()
sp.makeCloud((-0.3,-0.3,-0.05),(0.3,0.3,0.05),rMean=r)
sp.toSimulation(material=mat)
walls = O.bodies.append(ymport.stl('Drum.stl',material=mat2))
O.periodic = True
O.cell.setBox(5,5,0.2)
Based on the answers to some similar questions I also added
allowBiggerThanPeriod=True:
InsertionSortCollider([Bo1_Sphere_Aabb(),
Bo1_Facet_Aabb()],allowBiggerThanPeriod=True ),
But I get a very weird simulation.
Is the center of the created box using O.cell.setBox(5,5,0.2) on (0,0,0) ?
I was wondering if you could help me find where are my mistakes and how I can
apply the boundary condition in this case.
Regards,
Roxana Saghafian
