Exporting a model from Thermal Desktop to Simcenter 3D
Thermal Model Exchanger 2.0 introduces several significant improvements and new features for exporting models from Thermal Desktop into Simcenter 3D Space Systems Thermal. It now supports exporting domain tag sets, symbols, aliases, and more primitive, and boundary condition types from Thermal Desktop.
Exporting radiation
Thermal Model Exchanger 2.0 now converts radiation from Thermal Desktop to a Radiation simulation object of the Enclosure Radiation type.

What's new
- Importing a model from Simcenter 3D to Thermal Desktop
  Thermal Model Exchanger 2.0 introduces several significant improvements and new features for importing models from Simcenter 3D Space Systems Thermal into Thermal Desktop. It now supports a greater variety of mesh types, thermo-optical properties, and boundary condition types from Simcenter 3D.
- Exporting a model from Thermal Desktop to Simcenter 3D
  Thermal Model Exchanger 2.0 introduces several significant improvements and new features for exporting models from Thermal Desktop into Simcenter 3D Space Systems Thermal. It now supports exporting domain tag sets, symbols, aliases, and more primitive, and boundary condition types from Thermal Desktop.
  - Exporting primitives and domain tag sets
    Thermal Model Exchanger 2.0 now allows you to export more primitive types, control the primitive angular subdivision, and export domain tag sets from Thermal Desktop into Simcenter 3D Space Systems Thermal.
  - Exporting symbols
    You can now use Thermal Model Exchanger 2.0 to export symbol values from Thermal Desktop into Simcenter 3D Space Systems Thermal.
  - Exporting thermo-physical properties
    Thermal Model Exchanger 2.0 now supports enhanced export of thermo-physical properties, including scale values, specific heat, material stack and insulation properties, and optical and thermo-physical property aliases.
  - Exporting heaters and heat loads
    Thermal Model Exchanger 2.0 now supports exporting heaters with sense temperature selection from Thermal Desktop as thermal loads with thermostats or active heater controllers in Simcenter 3D Space Systems Thermal, and allows more options for heat load export.
  - Exporting radiation
    Thermal Model Exchanger 2.0 now converts radiation from Thermal Desktop to a Radiation simulation object of the Enclosure Radiation type.
  - Exporting orbits and space environment
    Thermal Model Exchanger 2.0 now supports exporting External Heating Environment boundary conditions from Thermal Desktop into additional types of orbital heating simulation objects in Simcenter 3D Space Systems Thermal.

Exporting radiation

Thermal Model Exchanger 2.0 now converts radiation from Thermal Desktop to a Radiation simulation object of the Enclosure Radiation type.

The surface selection in the exported Radiation simulation object of the Enclosure Radiation type varies depending on the active surface side in Thermal Desktop:

When the active surface side is both, the enclosure radiation has both top and bottom surface selections.
When the active surface side is top, the enclosure radiation has only the top surface selection.
When the active surface side is bottom, the enclosure radiation has only the bottom surface selection.

In previous releases, Thermal Model Exchanger converted radiation from Thermal Desktop to a Radiation simulation object of the All Radiation type.
