[gmx-users] The force unit in the gromacs

[齐文鹏]

Hello everynoe:
 
I simulate to stretch a DNA molecule. But there is no suitable methods, so I change the sorce of the Gromacs.
 
Before the update_md I add forces on some atomes. But I am not sure the force's unit is right or not.
 
 
In the manual, The forcce unit is kj/(mol*nm), so it is 1kj/(mol*nm) = 1.66 pn.
 
But during the calaulation, the force's unit changed or not? Can anyoe tell me the force unit during the calculation.
 
 
 
Thank you very much!!
