[gmx-users] Usage of GROMACS

[Momin Ahmad]

Hello Micholas,

thank you for the fast reply. Unfortunately i have bad experience with 
x2top and is no option for me (considering crystalline structures). I 
might have to look for other options.

Cheers
Momin

Typically, people working on MOFs, clays, general polymers, and other non-biological systems use something like LAMMPS (or DL_Poly like you have already noted). That being said, it isn't impossible to use gromacs for these types of systems, it just takes a bit of time.
