Hello,
I was trying to minimize the potential energy of a system of atoms without changing the lattice constants (and also the box size). I used the following commands to perform the minimization.
min_style sd
minimize 0.0 1.0e-8 50000 50000
However, I got “WARNING: No fixes defined, atoms won’t move” in my output log file. I’m wondering what’s going wrong.
Thank you!
