The Heat Transfer in Solids Interface
The Heat Transfer in Solids (ht) 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 in Solids to select physics features from the context menu.
By default, the shape functions used for the temperature in solids are Quadratic Lagrange.
See Settings for the Heat Transfer Interface and Feature Nodes for the Heat Transfer Interface for a description of all the settings and functionality.
