[lammps-users] stress-strain curve

Dear all,

I am trying to compute stress-strain curve for Silicon. Here is my input
subscript:

units metal
boundary s s p
.
lattice diamond 5.43
region box block 0 4 0 4 0 4
.
fix 2 all nvt 300 300 0.01
fix 3 all deform 1 z vel 10 units box #vel=10 Angstrom/ps
fix 4 all ave/time 1 100 100 c_thermo_press[3] file stress.all

Does c_thermo_press[3] give us the exact stress(zz) to plot the
stress-strain curve?

Regards,
Ali

It is Pzz. See the doc page for the formula.
