[CP2K-user] [CP2K:19152] Re: Souce to Learn Classical MD Simulation

Hi Sucharita, 

Is there a specific reason you want to use CP2K for classical MD? Because 
there are other software such as LAMMPS, GROMACS, HOOMD etc. which are more 
suitable for classical MD. 
For generating initial systems you can check out mbuild 
(https://mbuild.mosdef.org/en/stable/) and packmol 
(https://m3g.github.io/packmol/). 
The force field file template will depend on the software you choose for 
your MD simulations. If you just want to do classical MD, I would recommend 
using the software I have mentioned above. 

Best,
Ramanish
