compute smd/ulsph/num/neighs command
Syntax
compute ID group-ID smd/ulsph/num/neighs
ID, group-ID are documented in compute command
smd/ulsph/num/neighs = style name of this compute command
Examples
compute 1 all smd/ulsph/num/neighs
Description
Define a computation that returns the number of neighbor particles inside of the smoothing kernel radius for particles interacting via the updated Lagrangian SPH pair style.
See this PDF guide to using Smooth Mach Dynamics in LAMMPS.
Output info
This compute returns 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 page for an overview of LAMMPS output options.
The per-particle values will be given dimensionless, see units.
Restrictions
This compute is part of the MACHDYN package. It is only enabled if LAMMPS was built with that package. See the Build package page for more info. This compute can only be used for particles which interact with the updated Lagrangian SPH pair style.
Default
none
