pair_style smd/tlsph command :h3
[Syntax:]
pair_style smd/tlsph args :pre
[Examples:]
pair_style smd/tlsph
[Description:]
The {smd/tlsph} style computes particle interactions according to continuum mechanics constitutive laws and a Total-Lagrangian Smooth-Particle Hydrodynamics algorithm.
This pair style is invoked with the following command:
pair_style smd/tlsph
pair_coeff i j *COMMON rho0 E nu Q1 Q2 hg Cp &
*END :pre
Here, {i} and {j} denote the {LAMMPS} particle types for which this pair style is
defined. Note that {i} and {j} must be equal, i.e., no {tlsph} cross interactions
between different particle types are allowed.
In contrast to the usual {LAMMPS} {pair coeff} definitions, which are given solely a
number of floats and integers, the {tlsph} {pair coeff} definition is organised using
keywords. These keywords mark the beginning of different sets of parameters for particle properties,
material constitutive models, and damage models. The {pair coeff} line must be terminated with
the {*END} keyword. The use the line continuation operator {&} is recommended. A typical
invocation of the {tlsph} for a solid body would consist of an equation of state for computing
the pressure (the diagonal components of the stress tensor), and a material model to compute shear
stresses (the off-diagonal components of the stress tensor). Damage and failure models can also be added.
Please see the "SMD user guide"_PDF/SMD_LAMMPS_userguide.pdf for a complete listing of the possible keywords and material models.

[Mixing, shift, table, tail correction, restart, rRESPA info]:
No mixing is performed automatically.
Currently, no part of USER-SMD supports restarting nor minimization.
rRESPA does not apply to this pair style.
:line
[Restrictions:]
This fix is part of the USER-SMD package. It is only enabled if
LAMMPS was built with that package. See the "Making LAMMPS"_Section_start.html#start_3
section for more info.
