Question #655455 on Yade changed:

Jan Stránský proposed the following answer:
> Now I am trying to apply a force to this group of spheres:

you have to assign force to each sphere:
for sphere in spheres:
   O.forces.setPermF(sphere.id,(1,1,1)) # probably Vector3(1,1,1) / len(O.bodies)
   #O.forces.addF(sphere.id,(1,1,1),permanent=True)

or you can create a rigid clump instead of O.bodies.append (depending on your needs):
cid,bids = O.bodies.appendClumped(spheres)
O.forces.setPermF(cid,(1,1,1))
#O.forces.addF(cid,(1,1,1),permanent=True)

cheers
Jan
