Hi,

Thanks Axel,

It seems for me that I have only two options: Coarse-grained simulation with
an effective potential or ab initio molecular dynamics.

I was wondering if you could suggest a free software to performance
ab-initio molecular dynamics.

I took a look in google and wikipedia, but to be sincere, I am lost with all
the possible options!

I will really appreciate any help or suggestion.

Thanks a lot,

Salvador
