[gmx-users] Fwd: shift the LJ potential

I have a given function for pseudo hard-sphere potential, which has
different powers than LJ and a constant. I have to insert the constant in
order to properly define the cut-off for my hard spheres.
I just realized that I can use "user-specified potential". I guess I can
include the constant there, yes?
One more thing, I need to have my own particles, spheres with a diameter
"a". How can I have them in gromacs?

Shifting the potential doesn't affect the sampling - only the forces do.
How does that affect what you're thinking of?
