Conduction Command

The Conduction command activates thermal conductivity calculations and also activates various optionals involving heat flow in the simulations or other mechanisms that cause temperature changes. These settings can change and select the thermodynamics mode of the simulation.

Conduction (isOn),<(option1)>,<(option2)>,...

where

The optional parameters #2 etc. can activate various physical mechanisms as heat sources that may cause temperature rises and may change the thermodynamics of the analysis. The options are

Notes

  1. The default mode is "Isothermal". Use the "Adiabatic" option to switch to locally adiabatic instead. If both are listed, the last one listed will be the result.
  2. When conduction is on and/or the "Adiabatic" option is used, you must provide heat capacity for all materials used in the analysis to have realistic heat energy calculations. If conduction is on, you must also define thermal conductivity properties of materials used in the analysis.
  3. Conduction calculations often benefit by periodic FMPM, especially when particle temperatures oscillate with a cell.
  4. The Conduction command is only allowed for MPM analyses.
