compute smd/tlsph_strain command¶
Syntax¶
compute ID group-ID smd/tlsph_strain
- ID, group-ID are documented in compute command
- smd/tlsph_strain = style name of this compute command
Examples¶
compute 1 all smd/tlsph_strain
Description¶
Define a computation that calculates the Green-Lagrange strain tensor 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 of vectors (tensors), 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 tensor values will be given dimensionless. See units.
The per-particle vector has 6 entries, corresponding to the xx, yy, zz, xy, xz, yz components of the symmetric strain tensor.
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 SPH pair style.
