smd/tlsph/strain = style name of this compute command
compute 1 all smd/tlsph/strain
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.
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 the Howto output doc page 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.
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 quantity will be computed only for particles which interact with the Total-Lagrangian SPH pair style.
