bodies which are controlled by "setPermF" does not move. Is it right?
I have assigned permanent forces of 1,000 acting along the z-axis to the facets.
I expected that the facets will move due to the unbalanced forces (because it has no reaction forces).
However, it will not move at all. Does the contacting force of body is different with the conventional forces acting on the rigid body surface?
Thanks in advance.
