Re: Multi-Body Dynamics Simulation in Debian

[Drew Parsons <dparsons@debian.org>]

Multibody dynamics brings to mind molecular dynamics (gromacs, lammps), 
though you mean contact mechanics not atomistic dynamics.  Perhaps the 
MD software can be adapted to that though it would be a different kind 
of model (element-based contact modelling rather than continuum body 
modelling) .

We have a number of finite element packages (fenics, deal.ii) which can 
serve as the engine for contact mechanics, though you'd have to 
implement the weak formulation for your system to get it running 
(example scripts exist).

Does siconos do what you need?
