[gmx-users] Custom forcefield tutorial?

[Michał Kadlof]

Hello,

I would like to perform some simulations with my own simple forcefield.
Just a chain of beads, with Lenard-Jones, some harmonic and angle potential, and play with it's parameters.
I don't want to write all the computing part from the scratch. I rather to use Gromacs (if it is possible?), especially that MPI and GPU support is expected here.

I didn't find any suitable documentation or tutorial for this purposes.

Can you help me with this issue or give some advice?

cheers
Michal
