Descrizione

Definisce un calore generato internamente e ceduto in W/kg (non J/m³). Per maggiori informazioni vedere https://forum.freecadweb.org/viewtopic.php?f=18&t=44705&start=490#p422539 e seguenti e anche Elmer "Tutorial 1 - Heat equation – Temperature field of a solid object" in https://www.nic.funet.fi/pub/sci/physics/elmer/doc/ElmerTutorials.pdf.

version 1.0 and above: Can also define the heat source in W.

Utilizzo

Limitations

  • version 0.20 and below: The body heat source is applied to the whole model, meaning all bodies of the setup. It is not possible to select an individual body.
  • version 0.21 and below: This feature only works with the Elmer solver.

Notes

  • For more information see this forum thread and following posts. This thread may also be useful.
  • Elmer examples can also be found in Elmer GUI Tutorials.
  • version 1.0 and above: This feature uses the *DFLUX card in CalculiX.
  • version 1.0 and above: Since CalculiX expects body heat flux input in W/mm^3 while for Elmer it's W/kg, the conversion of the specified value (in W or W/kg) is done internally for each solver, using the volume of the selected solid and the density of the material assigned to it, if needed.
