Hi, and happy new year all! :-)

Non-dynamic aspherical standalone bodies (and probably also clumps) were
getting velocity updated in Newton.
It was breaking all triaxial simulations but the ones generated with the
preprocessor (the preprocessor set boxes spherical), and all scripts
with boxes (e.g. chained-cylinder-roots.py). r2635 is fixing this (as a
side effect).

There is nothing new in this commit; as suggested many times : don't
compute acceleration at all for DOF_ALL bodies, don't damp, and don't
update velocity. I think there was an agreement on the concept but it
was not fully implemented in 2626.
Undamping clump members will be the next step.

Best.

Bruno
