fix limit/vel command

Syntax

fix ID group-ID limit/vel vmax

  • ID, group-ID are documented in fix command

  • limit/vel = style name of this fix command

  • vmax = maximum velocity

Examples

fix lim all limit/vel 1.0

Description

If the velocity of a particle is larger than vmax, it is scaled down to vmax while keeping the direction of the velocity vector. This can be used to stabilize simulations by preventing artificially high velocities.
