fix couple/cfd/chemistry command

Syntax

fix ID group-ID couple/cfd/chemistry n_species Ns species_names s_names n_diff Nd diffusant_names d_names keyword value

  • ID, group-ID are documented in fix command

  • couple/cfd/chemistry = style name of this fix command

  • n_species = obligatory keyword

  • Ns = number of gas species flowing in

  • species_names = obligatory keyword

  • s_names = names of the relative gases

  • n_diff = obligatory keyword

  • Nd = number of diffusant names

  • diffusant_names = obligatory keyword

  • d_names = diffusant names

  • zero or more keyword/value pairs may be appended

  • keyword = transfer_reactant

    transfer_reactant value = yes or no

Examples

fix cfd3 all couple/cfd/chemistry n_species 5 species_names H2 H2O CO CO2 N2 n_diff 2 diffusant_names CO H2

Description

This fix exchanges chemical reaction relevant data between LIGGGHTS and CFDEMcoupling. Particle positions, velocities, radii and volumeweights are transferred from LIGGGHTS to CFDEMcoupling, the reacting gas species and product gas species from CFDEMcoupling to LIGGGHTS.

Restrictions

This fix needs a fix couple/cfd before it is defined.

Default

transfer_reactant = no
