I am trying simulate micellar systems like SDS, SDBS micelle in water. I
equilibrated the system for 20 ns using NPT Langevin piston.
Even after 20 ns run, the average temperature remained at 295 K for the
system (I am still pondering why this happened), so I used rescale velocity
(with rescalefreq 2 timesteps) for 500 ps.
After this I ran a NVE simulation (meaning, i switched off all the
thermostats and barostats) for about another 20 ns, the total energy of the
system seemed to change about 20000 units in the span of 20 ns.
I am using 1 fs timestep, with 2fs for non-bonded forces and 4fs for full
electrostatics. No rigidity imposed.
