[lammps-users] desired temperature

Hi all,

I am doing a polymer droplet simulation. Where I use the following
thermostatting method to get the
desired temperature.

compute mobile droplet temp
velocity droplet create 1.0 387093 loop geom
fix 1 all nve
fix 2 droplet langevin 1.0 1.0 1.0 468279
fix_modify 2 temp mobile
fix 3 substrate setforce 0.0 0.0 0.0

However, the values of the temperature are around 0.23. I expect it to
produce temperature about 1.0.
Can anyone tell me why this must be happening?


Are you printing the temperature of all the atoms or only
the mobile ones?
