compute sph/e/atom command
compute ID group-ID sph/e/atom
ID, group-ID are documented in compute command
sph/e/atom = style name of this compute command
compute 1 all sph/e/atom
Define a computation that calculates the per-atom internal energy for each atom in a group.
The internal energy is the energy associated with the internal degrees of freedom of an SPH particle, i.e. a Smooth-Particle Hydrodynamics particle.
See this PDF guide to using SPH in LAMMPS.
The value of the internal energy will be 0.0 for atoms not in the specified compute group.
This compute calculates a per-atom vector, which can be accessed by any command that uses per-atom values from a compute as input. See the Howto output doc page for an overview of LAMMPS output options.
The per-atom vector values will be in energy units.
This compute is part of the USER-SPH package. It is only enabled if LAMMPS was built with that package. See the Build package doc page for more info.
