[CP2K-user] [CP2K:15464] some issues with ab initio MD with xTB

[am...@gmail.com]

 Hi everyone, 
I am trying to do some ab initio MD simulation with xTB to evaluate the 
interatomic interactions. 
For a cubic cell with periodic boundary condition, for the same number of 
particles, as I reduce the number density (for the same number of particles 
only increasing the box size), the simulation time exponentially increases. 
Does any one have any idea? 
Best regards, 
Amin
