# 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.
