Hi,
I am interested in understanding when a force is applied ONLY to a member of
the clump, how it is transferred to the clump.
Bottom line is clump is/move always together, right?
Here is the code:
########################
O.materials.append(FrictMat(density=2e3,young=30e9,poisson=.3,frictionAngle=.5236))
# Material Used
##################### Defining Clump
O.bodies.appendClumped([sphere([5,5,5],1),sphere([7,5,5],1) ])
O.bodies.updateClumpProperties(discretization=100)
###############################
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack(sphericalBodies=False)]
),
PyRunner(command = 'applied_force()', iterPeriod = 1, label =
"checker"),
NewtonIntegrator(gravity=(0,0,0),damping = 0)
]
###############################
def applied_force():
O.forces.setPermF(0, Vector3(0,1.0,0))
O.dt = 5e-1*PWaveTimeStep()
O.stopAtIter= int(1e8)
O.run()
########################
The code works fine, shows the expected rotation and clump member stay
together.
O.forces.f(1) is Vector3(0,0,0) and O.bodies[1].state.vel is non-zero and
changing.
So how/step the applied force to a member via setPermF is transferred to the
clumped body to make it move as a single entity?
Can you please direct me to the right scripts?
Thanks.
Nishant
