By using this fix, I can not get the satifactory results. The temperature of
the system decreases to a very small value which is not the target
temperature . Do you have any tips to get the appropriate damping
parameters of temperature and pressure?
It takes me quite some time, until the temperature control works well.
I use 1000000 Steps just to equilibrate a 2000 atoms metal cell. You
probably should monitor the cell volume and the temperature and let it
run, until a steady state is reached.
