pair_style sph/heatconduction command
pair_style sph/heatconduction pair_coeff * * 1.0 2.4
The sph/heatconduction style computes heat transport between SPH particles. The transport model is the diffusion equation for the internal energy.
See this PDF guide to using SPH in LAMMPS.
The following coefficients must be defined for each pair of atoms types via the 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 pair_modify shift, table, and tail options.
This style does not write information to binary restart files. 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 run_style respa command. It does not support the inner, middle, outer keywords.
This pair style is part of the USER-SPH package. It is only enabled if LAMMPS was built with that package. See the Making LAMMPS section for more info.
