[lammps-users] Flow Problem: LAMMPS

Hi, I am new to LAMMPS. I am trying to set up a 2D-flow problem, where I use the LJ potential.
I want to modify the LJ potential to suit my interest. Can any one tell me how to do that?

If you're using pair_style lj/cut, then see the file src/pair_lj_cut.cpp

That's what you'd modify. Similarly for other pair potentials.
