Hi everyone,
<br>I am trying to do some ab initio MD simulation with xTB to evaluate the interatomic interactions.
<br>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?
<br>Best regards,
<br>Amin
