Dear all,

our Huimin Zhang is implementing some new integration schemes in MBDyn:

  * multi-stage schemes [1]
  * multi-step schemes, with 3 and 4 steps [2]
  * single-step variants of the multi-step schemes [2]

If you want to follow her progress, or contribute to it, please checkout 
the "integrators" branch from our gitlab repository 
<https://public.gitlab.polimi.it/DAER/mbdyn>.

Sincerely, p.
