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.

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.

By default, no check boxes are selected under the Physical Model section.

This section is available by clicking the Show button () and selecting Stabilization. See Consistent Stabilization for more details.

This section is available by clicking the Show button () and selecting Stabilization. See Inconsistent Stabilization for more details.

This section is available by clicking the Show button () and selecting Discretization.

By default, the shape functions used for the temperature in solids are Quadratic Lagrange.

In addition, the discretization level of the Irreversible transformation indicator should also be set when the Irreversible Transformation subfeature is added under a Solid node. Otherwise this setting has no effect.

See Discretization for more details.
