Hello Sergei,

Good to hear somebody is going for it.

Perhaps I don't understand what you need, but I am a bit surprised to 
hear it needs prevAngMom.
In the current scheme,  at time t, what you find in body->velocity is in 
fact velocity at time t-dt/2.

Introducing prevAngMom means you want a dependancy between 
AngMom(t+dt/2) and AngMom(t-3*dt/2).
It can happen for high (4th) order time discretisation, but it is really 
what you want now?

Bruno

p.s. Angular moment is rotational speed, right?
