Hi all,
In my simulation I have formed a spherical rigid body which contains a number of particles. The force that I get from fix rigid is exactly N times (N being the number of all atoms in my system) greater than what I get from “compute group/group” for the rigid body group from the rest of the field. Based on what I understand from the manual they should be the same, right? but I don’t know how this constant factor (N = number of atoms in the system) shows up there. I’d appreciate your comments on this.
Thank you,
Kasra.
