[gmx-users] nstcomm set to 10

[NG HUI WEN]

Dear gmxusers,

 

I have a question here concerning nstcomm.

 

I got the note below after doing grompp, I'd like to do something about
it.

NOTE 1 [file HW_NPT.mdp]:

  nstcomm < nstcalcenergy defeats the purpose of nstcalcenergy, setting

  nstcomm to nstcalcenergy

 

Currently, my nstcomm is set at 1 while nstlist at 10 (default
nstcalcenergy, nsttcouple, nstpcouple = -1). I would like to know, if I
set nstcomm to 10, therefore removing the center of mass motion every 10
steps instead of every step, will it adversely affect my simulation
(because the center of mass is allowed to move in between the 10-step
interval)?

 

I notice the default value for nstcomm is actually 10, so I gather
setting it to 10 should be OK?  Thank you.

 

HW
