.. index:: pair_style sph/heatconduction
pair_style sph/heatconduction command
=====================================
Syntax
""""""
.. parsed-literal::
pair_style sph/heatconduction
Examples
""""""""
.. parsed-literal::
pair_style sph/heatconduction
pair_coeff * * 1.0 2.4
Description
"""""""""""
The sph/heatconduction style computes heat transport between SPH particles.
The transport model is the diffusion euqation for the internal energy.
See `this PDF guide <USER/sph/SPH_LAMMPS_userguide.pdf>`_ to using SPH in
LAMMPS.
The following coefficients must be defined for each pair of atoms
types via the :doc:`pair_coeff <pair_coeff>` command as in the examples
above.
* D diffusion coefficient (length^2/time units)
* h kernel function cutoff (distance units)
----------
**Mixing, shift, table, tail correction, restart, rRESPA info**:
This style does not support mixing. Thus, coefficients for all
I,J pairs must be specified explicitly.
This style does not support the :doc:`pair_modify <pair_modify>`
shift, table, and tail options.
This style does not write information to :doc:`binary restart files <restart>`. Thus, you need to re-specify the pair_style and
pair_coeff commands in an input script that reads a restart file.
This style can only be used via the *pair* keyword of the :doc:`run_style respa <run_style>` command. It does not support the *inner*,
*middle*, *outer* keywords.
Restrictions
""""""""""""
This pair style is part of the USER-SPH package. It is only enabled
if LAMMPS was built with that package. See the :ref:`Making LAMMPS <start_3>` section for more info.
