Jan Stránský posted a new comment:
Hi guys,
just a theoretical comment concerning O.bodies.erase,. The memory of erased body is freed, but the space in BodyContainer remains (O.bodies.append does not reuse ids) and the size of BodyContainer itself is continuously increasing. So with continuous adding and deleting bodies, the simulation theoretically cannot be run indefinitely, but practically yes :-)
cheers
Jan

sphs = [sphere((2*i,0,0),1) for i in (0,1,2,3,4)]
s0,s1,s2,s3,s4 = sphs

O.bodies.append(s0)
O.bodies.append(s1)
O.bodies.append(s2)

print O.bodies[0], O.bodies[0].id
print O.bodies[1], O.bodies[1].id
print O.bodies[2], O.bodies[2].id
print len(O.bodies), len([b for b in O.bodies])

O.bodies.erase(0)
print len(O.bodies), len([b for b in O.bodies])
O.bodies.erase(1)
print len(O.bodies), len([b for b in O.bodies])
O.bodies.erase(2)
print len(O.bodies), len([b for b in O.bodies])

O.bodies.append(s3)
O.bodies.append(s4)
print len(O.bodies), len([b for b in O.bodies])
print O.bodies[0]
print O.bodies[4], O.bodies[4].id
