compute smd/ulsph/strain command
Syntax
compute ID group-ID smd/ulsph/strain
- ID, group-ID are documented in compute command
- smd/ulsph/strain = style name of this compute command
Examples
compute 1 all smd/ulsph/strain
Description
Define a computation that outputs the logarithmic strain tensor. 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 tensor, which can be accessed by any command that uses per-particle values from a compute as input. See Section 6.15 for an overview of LAMMPS output options.
The per-particle vector has 6 entries, corresponding to the xx, yy, zz, xy, xz, yz components of the symmetric strain rate tensor.
The per-particle tensor values will be given 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 compute can only be used for particles which interact with the updated Lagrangian SPH pair style.
