compute smd/vol command¶
compute ID group-ID smd/vol
ID, group-ID are documented in compute command
smd/vol = style name of this compute command
compute 1 all smd/vol
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.
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 the Howto output doc page 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.
This compute 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.
