The Heat Transfer in Shells (htlsh) interface (
), found in the
Thin Structures physics area under the
Heat Transfer branch (
), is used to model heat transfer by conduction, convection and radiation in layered materials represented by boundaries. The interface is active on all boundaries where a layered material is defined, with a
Solid model active by default. All functionalities for including other boundary contributions, such as surface-to-ambient radiation, are also available.
When this version of the physics interface is added, these default nodes are also added to the Model Builder:
Solid,
Thermal Insulation (an edge condition), and
Initial Values. Then, from the
Physics toolbar, add additional nodes that implement, for example, boundary interface or edge conditions, and heat sources. You can also right-click
Heat Transfer in Shells to select physics features from the context menu.
Select the applicable layers (the default setting is All layered materials) on which to apply the interface.
When a layered material stack or link is selected from the Layered Material list, unselect the check boxes corresponding to layers where the interface should not be applied in the
Selection table.
By default, the Heat transfer in porous media check box is not selected under the
Physical Model section. Select it to make the
Porous Medium boundary feature available, for the modeling of fractures.
By default, the shape functions used for the temperature are Quadratic Lagrange. This setting affects also the discretization of the temperature field in the thickness direction.
