Define Solar Heating Space

Create an enclosure, taking top and bottom element sides into consideration. See Radiation for more information.

Check the material properties for all elements in the enclosure. To model diffuse radiation within the enclosure, all elements must have emissivity defined. For solar spectrum radiative heating, all elements must have solar absorptivity defined. See Thermo-Optical Properties - Advanced dialog box (Thermal/SST/ESC/Multiphysics) for more information.

1. Choose Home tab→Loads and Conditions group→Solar Heating Space .

2. In the Solar Heating Space dialog box, select Latitude from the Type list.

3. Select a celestial body from the Planet list.If the celestial body you want to model is not on the list, select any celestial body and modify the solar flux values in the Solar Flux tab.

4. Select an option from the Orientation Method list to specify the model orientation is defined.

5. On the Model Orientation tab, in the Planet Vector group, define the required vectors to orient your model.

6. (Optional) In the Solar Vectors group define the section of the day you want to simulate.

7. On the Solar Flux tab, select a point in time from the Time of Year list.

8. Click OK.
