Dear all,
I am conducting a simulation of a protein membrane system. I have
decided to split the simulation on 1 ns step, saving energies and
coordinates every 10 ps. I am using NPT ensemble (Langevin) using
ConstantRatio.
After 10 ns I noticed a shift on the TOTAL energy (contributed mainly by
ANGLE + DIHEDRAL + KINETIC ) and TEMP around step 10420000. The ENERGY
returns to previous values only when I restarted the simulation on step
11000000.
Any clue on what might be happening? And what should I do? Discard this
data and resume from step 100000?
