Hi,

Does anyone know where I can get hold of a molecular dynamic simulation software? Preferably a free one?

Thanks

GAMESS has a free license. it has an MD function. I've never tried it but I am pretty sure it works

NWChem is a nice bit of software.  You gotta apply to get it from the site, but that's pretty common.  It uses AMBER forcefields and all that to run semi-empirical calculations, but I'm pretty sure it can step up to ab initio...

It SHOULD be free, but I'm not absolutely certain if you're not a professor.  Worth a shot anyway, since it's not a bad program at all!
