Parameter definition

$v_{max}^{N}$ Maximum allowed node velocity
default: no upper limit
$v_{max}^{DP}$ Maximum allowed discrete particle velocity
default: no upper limit


This command is used to define an upper limit for node and discrete particle velocities. The purpose it to prevent single nodes or particles, that (for numerical reasons) have reached extreme velocities, from destroying the simulation results. Nodes and particles that are moving too fast are simply brought back to the specified maximum allowed levels.
