jasperb is still having a problem:
Hey I am close to the answer！
I have generated a sphere-like clump composed of 1,000 spheres and assigned
bonds to them using JCFpm.
1.But the issue is that it seems that I cannot control the overall breakable
"clump" ? I mean I could not assign a desired initial velocity simply to the
whole clump. And a workaround may be that I assign the initial velocity for
each of the member spheres? Does that make sense？
2. As a breakable clump, there already exists thousands of interactions. But it
seems that I could not check the interaction information by
O.interactions[#particleID1,#particleID2] (the traditional way). YADE will say
that no such interactions when I check O.interactions[0,1].phys……. And it works
when I use the loop. For i in O.interactions: …… Is there any way that I can
just check the desired contact pair?
3. I want to make the breakable clump impact with a layer of spheres. And I
want to record the time when the impact takes place by the function as
O.interactions.countReal()>0. But there are already thousands of interactions
inside the breakable clump. Is there any way I could ignore the inside
contacts temporarily so that I could capture the impact moment?
Thanks!
Jasper
