Hi, I am trying to make several clumps move on the x-axis at a constant
velocity. I have written a function that will be used by PyRunner to repeatedly
spawn these clumps every so many iterations. My function currently works if I
just append the packing as spheres but when I change them into clumps they
remain static on the x-axis. However, the clumps do move if I use
NewtonIntegrator and apply an acceleration on the x-axis.
Here is my function:
def moreSpheres(i=1):
y_shift = 0
for n in xrange(0,i):
geoFile = 'ice_blocks/ice_block_'+str(random.randint(1,1000))+'.geo'
y_shift+= random.uniform(10, 15)
x_shift = random.uniform(0, 20)
packing = yade.ymport.gengeoFile(fileName=geoFile,
shift=Vector3(-99+x_shift, -99+y_shift, 2), scale=1.0,
orientation=Quaternion((1, 0, 0), 0),color=sphereColor, material=ice,
wire=False)
for b in packing:
b.state.blockedDOFs='xYZ'
b.state.vel = Vector3(50,0,0)
#O.bodies.appendClumped(packing)
O.bodies.append(packing)
Thank you,
Colin Power
