compute smd/rho command
compute ID group-ID smd/rho
- ID, group-ID are documented in compute command
- smd/rho = style name of this compute command
compute 1 all smd/rho
Define a computation that calculates the per-particle mass density. The mass density is the mass of a particle which is constant during the course of a simulation, divided by its volume, which can change due to mechanical deformation.
See this PDF guide to use 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 How-to discussions, section 6.15 for an overview of LAMMPS output options.
The per-particle values will be in units of mass over volume.
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.
