Solar Heating Space dialog box(SST)

Option Description
Type Specifies how the software calculates the direct solar view factors.Illuminate All ElementsAllows the solver to determine which elements are illuminated.Illuminate Selected ElementsAllows you to limit the solver's search for illuminated elements to only the elements you select. This can save calculation time when it is obvious that some parts of the model have no direct view of the source.
Name
Name Lets you specify a name for the simulation object.
Destination Folder
Simulation Object Container Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Illuminated Region/Region Illuminated on Top Side/Region Illuminated on Bottom Side
Group Reference Lets you apply the top or bottom illuminated region to a group.For more information, see Group Reference options.
Select Object Lets you select the geometry (or associated elements) to illuminate on the top and bottom sides.For Region Illuminated on Top Side only,Element Selection Filtering lets you limit your element selection to the FE entity you select from the Filter Type list:0D Elements, 1D Elements, or 2D Elements lets you select only elements of that order.Element Edges lets you select only the edges of 2D elements.Element Faces lets select only the faces of 3D elements.Excluded lets you remove individual entities from within your selected object.
Stacked Smart Selector Methods Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Parameters
Planet Specifies the celestial body on which the model is situated.When you select a celestial body, values on the Solar Flux tab are automatically populated.You can modify these values to model specific scenarios or other celestial bodies.
Orientation Method Specifies how the software calculates solar and earth view factors.LatitudeSpecifies the location on the earth in terms of latitude. Type an angular value (south is negative) in the Latitude box.Sun Earth VectorsSpecifies the direction of the sun and the earth at each calculation point during the analysis.The option you select for the Orientation Method list determines displayed options on the Model Orientation tab.
Calculation Method Specifies how the software calculates the view factors.DeterministicUses the deterministic view factor method to calculate radiative heating. Specify an Element Subdivision value to balance view factor accuracy against calculation speed.Monte CarloUses the Monte Carlo calculation method. For more information, see Understanding the Monte Carlo calculation method.
Element Subdivision Available when Calculation Method is set to Deterministic.Balances view factor accuracy against calculation speed.Fixed granularitySets the granularity of the element subdivision for computing shadowed view factors. Select one of five levels of granularity numbered 0 to 5. A higher subdivision level yields more accurate radiative conductances, but the computation requires additional time. Use GlobalUses the global element subdivision that you specify for the Element Subdivision option on the Radiation Parameters page in the Solver Parameters dialog box.Based on Error CriterionDynamically estimates a subdivision level for each view factor, using the lowest subdivision level that satisfies the criterion. You specify a view factor error tolerance for computing shadowing checks in the Criterion Value box.
Monte Carlo Settings Available when Calculation Method is set to Monte Carlo.Lets you choose a previously defined Monte Carlo Settings modeling object from the list or click Create Modeling Object to create a new one. See Monte Carlo Settings for more information.
Include Faces of Solid Elements Available only for the Illuminate All Elements type.Models radiation from the surfaces of solid elements.Clear the check box to have these surfaces ignored for radiation.
Model Orientation tab
Defines the model orientation for solar heating. For more information, see Solar Heating Space – Model Orientation.
Solar Flux tab
Defines or computes the solar flux. For more information, see Solar Heating Space – Solar Flux.
Card Name Displays the name of the associated solver card.
