compute smd/damage command — LAMMPS 15 May 2015 version documentation

# compute smd/damage command

## Syntax

    compute ID group-ID smd/damage

- ID, group-ID are documented in compute command
- smd/damage = style name of this compute command

## Examples

    compute 1 all smd/damage

## Description

Define a computation that calculates the damage status of SPH particles according to the damage model which is defined via the SMD SPH pair styles, e.g., the maximum plastic strain failure criterion.

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

Output Info:

This compute calculates a per-particle vector, which can be accessed by any command that uses per-particle values from a compute as input. See How-to discussions, section 6.15 for an overview of LAMMPS output options.

The per-particle values are dimensionless an in the range of zero to one.

## Restrictions

This compute is part of the USER-SMD package. It is only enabled if LAMMPS was built with that package. See the Making LAMMPS section for more info.
