Hi, I can see that there are several options in lammps to do twisting of the particles. Is anyone aware whether the following proposed fix (fix twist) in the links below is available in the latest version of lammps? Can “fix twist” be replaced with another name? https://www.youtube.com/watch?v=tnhUKxsAaqw or https://www.youtube.com/watch?v=TzCJ4BTUQ20 Thanks, Hadi …
