Robert Caulk requested more information:
Hello,

Why are you creating and adding many new RotationEngines. Apparently you
add a new engine for every single spherical body in your scene...this is
not right.

>>I would like to stop the rotation of the drum at a certain point and
rotate with respect to the rotation axis of the drum , only the set of
all the particles by a certain angle dtetab for a single time step, in
order to get the image of the flow after this rotation( angle dtetab).

Please rephrase this, I do not understand it. It sounds like you want to
stop the rotation, and then start the rotation around some new axis of
the drum? You only want some of the particles to rotate? This is all
quite confusing. It needs to be fully rewritten before anyone can help
you here.

Cheers,

Robert
