Hi All.

I am a new bee to LAMMPS, and trying to find out the Critical Resolved Shear Stress for pure Cu with one edge dislocation. My orientations are x 1 1 0 y -1 1 1 z 1 -1 2…

I am defining the atom coordinates, and input them to LAMMPS, and performing energy minimization. What i see is that the simulation box is continously increasing in size when i am using fix 1 all box/relax iso 0.0 command, while the atoms seem to be where they are. Can someone help please…??? I am attaching the i/p file.

Can i please get the input files of someone who has one it.....

posting the same e-mail over and over again will not get
you any closer to have your problems resolved. on the
contrary, you will just make people angry.

as has been stated multiple times already, nobody can
help you with the incomplete information that you are provide.
