Thermal Expansion (for Materials)
Use the Thermal Expansion subnode to add an internal thermal strain caused by changes in temperature.
Shell Properties
Select the layer or layers for which this thermal strain contribution is to be added.
When Use all layers is not selected.
If the Input type differs between layers, you will need to add several Thermal Expansion nodes with different layer selections. If only the material data values differ, you can use a single Thermal Expansion node with From material. The data for each layer is then received from global Layered Material nodes.
If the same layer is selected in two Thermal Expansion nodes being active on the same boundary, the second definition will override the previous.
When adding a Thermal Expansion subnode, and the temperature field is computed by another physics interface (often the Heat Transfer in Shells interface); use a discretization one order lower for the temperature field than what is used for the displacement field.
All other settings for the Thermal Expansion node are described in the documentation for Thermal Expansion (for Materials) in the Solid Mechanics interface.
