Dear Saif,

There is no difference, really. You compute the forces with ab-initio methods, 
and evolve
the ions using Newton's equations with those forces. You had bad luck with the 
referee.

| Dear Alberto,
| 
| Thank you very much for your answer. Once, we used "ab initio" in a
| paper (using SIESTA) and one reviewer asked (badly insulted) to change
| this. We discussed it in the light of Newton's equation, Car-Parrinello,
| Born-Oppenheimer, Pseudopotentials etc, but our paper was accepted only
| when we changed the AIMD to MD in the third round of review. Here, I
| would take the liberty to ask you about the difference in MD between
| SIESTA and the other mentioned code?
| 
| Regards,
