Almost all physics nodes that you add in the Heat Transfer in Shells interface have either a section named Layer Selection, or a section named Interface Selection. Selections there interact with the standard selections of geometrical objects (boundaries and edges) in order to provide a complete specification of where a material property or boundary condition is to be applied.

Several selections are available in the Layer Selection and Interface Selection sections, depending on the physics features. In the Layer drop-down list, you can select

If you select All layered materials, you cannot control individual layers; the contribution is given to all layers. All information is taken from the definitions made in the layered material features (Layered Material Link, Layered Material Stack, or Single Layer Material) under Materials in the current component. This means that a single physics node can accommodate several different stacking sequences. As geometrical selection, you can use any object selected in any of the layered material features.

If you select an individual Layered Material Link, Layered Material Stack, or Single Layer Material, then you can only select geometrical objects which are part of the selections of that feature. In most cases, you will get access to a list of check boxes where you can further limit the contributions to individually selected layers or interfaces to which this contribution is to be added.

This is illustrated by Figure 5-1 and Figure 5-2, where the patch at the lower left is the actual shell, and the 3D sketch shows an expanded view of what it would represent in the physical world.
