In the heat transfer interfaces, most of the features (equations and variables) are defined in the spatial frame, excluding Solid, Biological Tissue, Building Material, Shape Memory Alloy and Battery Layers features, which are defined on the material frame. When a moving mesh is detected, the user inputs for certain features are defined in the material frame and are converted so that all the corresponding variables contain the value in the spatial frame.

The following explains the different values listed in the definition frame column in Table 3-8, Table 3-9, and Table 3-10:

For these physics nodes, select from the Material type list to decide if the inputs are defined in the material or spatial frame. The default definition frame is the material frame, which corresponds to Solid in the Material type list.

For these physics nodes, select from the Material type list to decide if the inputs are defined in the material or spatial frame. The default definition frame is the spatial frame, which corresponds to Nonsolid in the Material type list.
