[ODE] high accuracy cable physics

[Gazi Alankus]

Having said all this, what are some simulation libraries that do more
or less what ODE does and are scientifically accurate? Of course they
don't have to be realtime at all.

I searched for Stewart-Trinkle time stepper but didn't find anything
useful except this link:
http://www.cs.rpi.edu/~trink/sim_packages.html

Could anybody recommend such libraries? I'll use it offline to verify
things I do in real time in ODE.
