Would not just be simply an initial velocity you assign, which might
change once your body hits another one, isn't it?
In that case, you just assign an initial velocity (body.vel=.., no
engine, no blocked DOF). This is not what I call a
"prescribed-something" body, just the usual dynamic body with some
initial conditions.
We could ideally also define a coefficient of restitution, that would
be equal to one if no dissipation occurs during the impact. Why do you
think this is not understandable?
In my understanding, "restitution coefficient" results from
Newton+contactLaw, not from artificialy controling the displacement or
velocity.
Also, kinetic energy of velocity/displacement controlled bodies
should not count in the total kinetic energy, only
prescribed-force bodies should.
I cannot see why not..
I was not reffering to bodies with an initial velocity, but bodies which
are not subjected to Newton's law. They had no kinetic energy to the
system since they are not dynamic (motion not modified by mass).
Chiara, did you try the blockedDOF trick?
I try. I let you know.
Well, perhaps it was irrelevant. I still don't know what you are looking
for...
For initial velocities at least, blockedDOFs are useless.
Ciao.
