[CP2K-user] Forces in BOMD calculations

[Dmitrii Nikolaev]

Dear collegues,

I am running the Born-Oppenheimer molecular dynamics, and I notice that the 
sum of the forces on all atoms of my molecule is non-zero. However, as I 
understand for the NVE ensemble the total force should be zero? What is the 
reason for this force? 

Thank you in advance,
Dmitrii
