fix couple/cfd/convection command

Syntax

fix ID group-ID couple/cfd/convection keyword values

  • ID, group-ID are documented in fix command

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

  • zero or more keyword/value pairs may be appended

  • keyword = T0 or transfer_conduction or max_change

    T0 value = initial temperature for new particles
transfer_conduction value = yes or no (default no)
max_change value = maximum change of temperature per particle per time step

Examples

fix cfd1 all couple/cfd/convection T0 293

fix cfd2 all couple/cfd/convection T0 293 transfer_conduction yes

fix cfd3 all couple/cfd/convection T0 293 max_change 0.1

Description

This fix pulls data for convective (and optionally conductive, if modeled in a Eulerian fashion) heat fluxes for each particle from CFDEMcoupling and passes them to a scalar transport equation. The maximum change of temperature for each particle may be limited to enhance numerical stability.

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