MD energy conservation: improved algorithms?

#1 Post by protonic » Wed Jun 08, 2011 6:27 pm

MD energy conservation can be improved by using tighter electronic convergence, projection in reciprocal space, and reducing the time step. Very recently however, I found out that upgrading to Vasp 5.2 gives significantly better MD energy conservation (for SMASS=-3) without having to use much more computing time.

And so my question is: how exactly did the molecular dynamics algorithms change from Vasp 4.6 to 5.2? Thanks in advance.
