I have a question about the command fix lj/wall93.
The manual said for the fix lj/wall command, the units keyword determines the meaning of the distance units used to define a wall position. However, I wander if it also determines the energy units, as the epsilon is energy or energy/distance^2 units.
Because I’m doing a simulation that the units is real, not lj, so I don’t know whether the command “fix wallhi all wall/lj93 xlo v_x 1.0 1.0 2.5 units box” can be used in my system without conversion. I mean, do I need to calculate the value of epsilon for the units real?
I don’t know if I am making myself clear. Thanks for reading my question!
