### compute smd/tlsph_num_neighs command

Syntax:

    compute ID group-ID smd/tlsph_num_neighs

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

Examples:

    compute 1 all smd/tlsph_num_neighs

Description:

Define a computation that calculates the number of particles inside of the smoothing kernel radius for particles interacting via the Total-Lagrangian SPH pair style.

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 values are dimensionless. See units.

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.

This quantity will be computed only for particles which interact with the Total-Lagrangian pair style.
