On the Constituent Physics Interfaces
The Solid Mechanics interface is described in The Solid Mechanics Interface of the Structural Mechanics Module User’s Guide.
Settings for Physics Interfaces and Coupling Features
The following checkboxes are selected in the Austenite Decomposition interface:
The discretization for the temperature field in the Heat Transfer in Solids interface is set to Linear, because thermal strains are typically linear in the Solid Mechanics interface.
