Beschreibung
Definiert eine intern erzeugte Körperwärme, angegeben in W/kg (nicht J/m³). Siehe https://forum.freecadweb.org/viewtopic.php?f=18&t=44705&start=490#p422539 und folgende sowie Elmer "Tutorium 1 - Wärmegleichung - Temperaturfeld eines Festkörpers" in https://www.nic.funet.fi/pub/sci/physics/elmer/doc/ElmerTutorials.pdf für ausführlichere Informationen.
Anwendung
- There are several ways to invoke the command:
- Press the
FEM ConstraintBodyHeatSource button. - Select the Model → Thermal Constraints → Constraint temperature option from the menu.
- Press the
- In the 3D view select the objects the constraint should be applied to, which can be a vertices (corners), edges, or faces.
- Enter a specific heat value to apply to the objects.
Notes
- For more information see this forum thread and following posts.
- Elmer examples can also be found in Elmer GUI Tutorials.
