### compute smd/vol command

Syntax:

    compute ID group-ID smd/vol

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

Examples:

    compute 1 all smd/vol

Description:

Define a computation that provides the per-particle volume and the sum of the per-particle volumes of the group for which the fix is defined.

See this PDF guide to using 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 vector values will be given in units of volume.

Additionally, the compute returns a scalar, which is the sum of the per-particle volumes of the group for which the fix is defined.

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.

Default: none
