Hi all,
I've got a confusing problem. I have a Langevin thermostat in my system and I put particles in my simulation box. Every time I run for a 1000 time steps and print the position of a specific particle, I've got exact same X Y Z for that particle in all of my runs. So how can I simulate movement of a drop of ink in water (Diffusion)?
Is there any seed for randomness in Langevin?
" system.thermostat.set_langevin(kT=1.2, gamma=1.0) "
By the way happy new year.
