Re: clumps


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?


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

Sergei D. a écrit :
In order to realize the accurate rigid body rotation integrator I need
the previous angular moment. So, can I add prevAngMom to the State class
or would be better if I add it to a RigidBodyState class which derived
from the State?

Best regards, Sergei D.
