You can apply a film condition that has different film coefficient values or reference
temperature values at different points on the model. You can choose to apply mapped
data for either the film coefficients, the reference temperatures, or
both.
Note:
Create a temperature initial condition to
establish the starting temperature before solving any simulation with
temperature-dependent features.
Before you begin: You must have your spatially mapped data prepared. The mapped data specifies different
film coefficient values or reference temperature values at various points in
space.
-
From the Thermal section of the action bar, click Film Condition
.
- Optional:
Enter a descriptive
Name.
-
Select the geometry supports in the model.
You must apply a film condition to one or more faces.
-
From the Film Coefficient options, select
Mapped spatial data.
-
From the Ref. Temperature options, select
Mapped spatial data.
The reference temperature is the temperature surrounding the selected
faces.
- Optional:
Click
to scale the magnitudes of either set of mapped values:
- Enter a Scale factor that is applied to the magnitude in each step.
- Select an
Amplitude that
defines the magnitude during the
step.
-
To specify your mapped data for film coefficients and reference
temperatures, click Table.
The Film Coefficient Distribution dialog box
or Temperature Distribution dialog box opens, where
you can enter or import the mapped values.
-
Choose the Data source for the mapped values:
- Table: Enter or import the mapped data into
the table. To import the data, right-click anywhere in the table and
select Import. To enter the data manually,
double-click in each cell and enter a value. For example, enter X-, Y-,
and Z-coordinates and the corresponding Value in
each row of the table.
-
Referenced document: Select a 3DEXPERIENCE document that contains the mapping data. Click 
to search for the document in the 3DEXPERIENCE platform database.
Changes in the referenced document are taken into account every time
you run the simulation.
For information about the required
file format, see Mapping Data File Formats.
-
Enter a value as the Film coefficient outside the mapped
region or the Temperature outside the mapped
region.
The simulation attempts to map all of the source data points and their
associated values onto points in the target model. For any target points
where the simulation cannot map to a source point, it substitutes this
default value.
-
From the Axis system definition options, select one
of the following:
| Option | Description |
|---|
| Global |
Aligns the local feature triad with the global coordinate
system. |
| Local |
Aligns the local feature triad with a selected axis system in
the model. |
Using a custom local axis system simplifies the three-dimensional
definition of points in space—the X-, Y-, Z-coordinates are interpreted in
the context of the local coordinate system.
-
Optional: Select Plot Data to display
symbols that indicate the locations and magnitudes of the mapped values on
the model.
-
Optional: To adjust the search control parameters, expand the
Search tolerance.
For descriptions of these parameters, see
Mapping Search Controls and Mapping Search Control Options.

Click OK.
