When the predefined Heat Transfer with Orbital Thermal Loads interface (
) is added (found under the
Heat Transfer branch (
) of the
Model Wizard or
Add Physics windows), it combines the Heat Transfer in Solids and the Orbital Thermal Loads interfaces to model heat transfer in a spacecraft, combined with the orbit and solar irradiation computation.
As a predefined multiphysics coupling, Heat Transfer in Solids and
Orbital Thermal Loads interfaces are added to the Model Builder. In addition, a
Multiphysics node is added, which automatically includes the
Heat Transfer with Surface-to-Surface Radiation multiphysics coupling feature.
The Heat Transfer in Solids interface provides features for modeling heat transfer by conduction, convection, and radiation in optically thick media. A Solid model is active by default on all domains. All functionality to include other heat transfer models, and thermal boundary conditions, is also available.
The Heat Transfer with Surface-to-Surface Radiation multiphysics coupling is also available when there is at least one of each of the following interfaces with the specified model activated:
