effm command¶

Syntax¶

compute ID group-ID smd/ulsph/effm

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

Examples¶

compute 1 all smd/ulsph/effm

Description¶

Define a computation that outputs the effective shear modulus 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 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 page for an overview of LAMMPS output options.

The per-particle vector contains the current effective per atom shear modulus as computed by the pair smd/ulsph pair style.

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
