The Heat Transfer in Solids Interface
The Heat Transfer in Solids () interface is used to model heat transfer in solids by conduction, convection, and radiation. A Solid model is active by default on all domains. All functionality for including other domain types, such as a fluid domain, is also available.
The temperature equation defined in solid domains corresponds to the differential form of the Fourier’s law that may contain additional contributions like heat sources.
When this version of the physics interface is added, these default nodes are added to the Model Builder—Solid, Thermal Insulation (the default boundary condition), and Initial Values. Then, from the Physics toolbar, add other nodes that implement, for example, boundary conditions and sources. You can also right-click Heat Transfer is Solids to select physics features from the context menu.
Discretization
By default, the shape functions used for the temperature are Quadratic Lagrange.
To display more than the shape functions in this section, click the Show More Options button () and select Advanced Physics Options in the Show More Options dialog box. See Settings for the Heat Transfer Interface for a description of the other settings.
See Table 2-4 for links to common sections and Table 2-5 to common feature nodes. You can also search for information: press F1 to open the Help window or Ctrl+F1 to open the Documentation window.
