Hi All,
When heating, I found that people have used very slow heating (heating
linearly to 300ps) to bring up
the temperature from 0K - 300K)
reassignFreq 1
reassignIncr 0.001
reassignHold 300
numsteps 300000
timestep = 1fs
So basically, increases the temperature by 0.001 degK every step 1degK/ps
Is that too slow and will it affect my simulation later on? I realize that
increasing the heat too fast can lead to a massive input of kinetic energy
in too short a time and that can cause the system to go haywire.. but what
about too slow heating? Since I am trying to unfold the protein
I want to make sure that the heating is slow and nice. Any thoughts?
Regards,
Arun
