fix smd/integrate_tlsph command

Syntax

fix ID group-ID smd/integrate_tlsph keyword values

  • ID, group-ID are documented in fix command

  • smd/integrate_tlsph = style name of this fix command

  • zero or more keyword/value pairs may be appended

  • keyword = limit_velocity

limit_velocity value = max_vel
  max_vel = maximum allowed velocity

Examples

fix 1 all smd/integrate_tlsph
fix 1 all smd/integrate_tlsph limit_velocity 1000

Description

The fix performs explicit time integration for particles which interact according with the Total-Lagrangian SPH pair style.

See this PDF guide to using Smooth Mach Dynamics in LAMMPS.

The limit_velocity keyword will control the velocity, scaling the norm of the velocity vector to max_vel in case it exceeds this velocity limit.

Restart, fix_modify, output, run start/stop, minimize info:

Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.

Restrictions

This fix is part of the USER-SMD package. It is only enabled if LAMMPS was built with that package. See the Build package doc page for more info.
