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 MACHDYN supports restarting nor minimization. This fix has no outputs.

Restrictions

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

Default

none
