Hi Ken,

please do not contact me directly, use the

This is a shorter way:

O.bodies.append([utils.sphere([0,0,i],1) for i in range(21)])

Bound dispatcher takes _list_ of functors. That line must read

  BoundDispatcher([Bo1_Sphere_Aabb(aabbEnlargeFactor=intradius)])

It is more efficient to assign O.engines at once:

O.engines=[ForceResetter(),BoundDispatcher([...]),...]

(See also simulations in the examples directory, for more complicated
stuff.)

(This message is somewhat confusing (although true) and it was fixed in
the development version of yade.)

Cheers, Václav
