Dear lammps users,
I have a question about the read_restart command. My model is a pristine single crystal Al nanopillars with a length-to-diameter ratio of 2:1, at first, the energy was minimized, then the arrangement was relaxed for 10000 time steps at 10 K. After that, uniaxial compression was performed by imposing compressive displacements to atoms along the z-direction that varied linearly from zero at the bottom to a maximum value at the top layers. the simulation was performed in constant NVT ensemble.
I wrote restart file after relaxing and when I used the relaxed configuration to perform compression directly, the result was tensile! Other parts were the same. I attached the two input files, you can test them.
Hope to get some advice from you.
