time integration

Submitted by teenut567 on Sat, 11/22/2014 - 18:41

Hi everybody,

how is the acceleration of velocity calculated for every time step in LIGGGHTS?
Is it the same way like in PFC (using the central difference quotient)?

Hi,

LIGGGHTS uses a velocity verlet integration by default. But it's very simple to modify the integration (fix nve/sphere)

Best wishes
