segmentation fault

Dear all,

I am writing my first code in lammps. What I am trying to do is run a simple nve simulation to see if my structure holds up at room temperature. Unfortunately, I got a segmentation fault error before the code starts to run.

I’ve attached my input script here in the hope that someone might know what i did wrong. The code stopped before ‘segfault1’.

Never set sigma in a lj potential to zero.
