Preparing Scenes

Specific Heat, Thermal Conductivity, and Density

These buttons generate scenes showing contours of specific heat, thermal conductivity, or density for the vehicle exterior or interior solids. The exterior scene includes all solid regions that do not have “road” in the name and are on the exterior of the model; it is intended for models in which the windows, doors, and other panels are modeled as solids. The interior scene is used to display contours on solid regions on the interior of the model, which are identified as those with “seat” in the name. If there are no solid regions in the model, these buttons are not activated.

Thermal Emissivity and Solar Emissivity

These buttons generate scenes showing contours of thermal emissivity or solar thermal emissivity for the exterior and interior surfaces of the fluid regions (not solid regions). The exterior scene displays contours on all fluid boundaries in the model, whereas the interior scene only includes boundaries that have “seat” in their name. If the model does not include a radiation model, these buttons are not activated.

It is assumed that two separate radiation spectral bands have been defined in the model, and that the first band has lower wavelengths (that is, is solar radiation), while the second band has higher wavelengths (that is, is non-solar radiation). For the Solar Emissivity scenes, the emissivity values for the first band are displayed. For the Thermal Emissivity scenes, the emissivity values for the second band are displayed.

Displaying Sun Location

For a case where the sun has been included in the simulation by using the Solar Loads model, the Sun Location button can be used to give a visual indication of the location of the sun. The sun is represented in the model by a sphere, and its position is calculated automatically based on the Azimuth and Altitude Angles you have specified in the solar load properties.

When you click the Sun Location button:

• A new sphere part is created;
• A new Sun Location scene is created;
• The fluid region and the sun part are displayed in the scene.

You are able to view this scene once you have closed the thermal comfort wizard.

Displaying All TCM-Specified Boundaries

Clicking the All TCM-specified Boundaries button creates a geometry scene displaying all boundaries specified within the thermal comfort wizard’s External Convection and Radiation tab. This is useful for identifying the boundary types assigned in the thermal comfort wizard, and quickly creating scalar or vector scenes with the TCM boundaries by adding scalar or vector displayers.

The TCM boundaries are categorized with a different geometry displayer for each boundary type.

A mesh color is applied to each scene displayer to visually distinguish between TCM boundary types. The scene displayers, equivalent TCM boundary type, and mesh color are summarized below:

Heat Transfer Coefficients

Clicking the Heat Transfer Coefficients button creates a scalar scene displaying the heat transfer coefficients for all solid regions and boundaries. This speeds up the solution monitoring and post-processing requirements by automatically creating a heat transfer coefficient scene with typical settings and boundaries.
