[ODE] high accuracy cable physics

[François Bruneau]

Thanks all for your answers.

The overall feeling I get is that ODE is good for approximate
simulations, not precise calculations.

Anyway, that might just what I need. The cable simulator I'm
considering has a 20% error tolerance on static position.

Did any of you carry out a validation work, i.e. comparing
ODE-generated results with real world experimental results ?

Thanks again,

François.
