16.11.6 Defining a fluid thermal energy field

You can create a fluid thermal energy field to define the initial value of fluid temperature in an Abaqus/CFD analysis. For more information, see Chapter 30, Fluid dynamic analyses.”

To create or edit a fluid thermal energy field:

  1. Display the fluid thermal energy field editor using one of the following methods:

    Note:  You can create or edit a fluid thermal energy field only in the initial step. For more information, see Chapter 30, Fluid dynamic analyses.”

  2. By default, the fluid thermal energy field is applied to the whole model. If you want to change the region for which the fluid thermal energy field applies, do the following:

    1. Click .

    2. Select one or more regions or sets from the viewport.

    3. From the prompt area, click Done.

    Abaqus/CAE updates the fluid thermal energy field editor to reflect your selection.

  3. Click the arrow to the right of the Distribution field, and select the option of your choice from the list that appears:

    • Select Uniform to define an initial fluid temperature that is uniform over the region.

    • Select an analytical field, labeled with an (A), or a discrete field, labeled with a (D), to define a spatially varying initial fluid temperature. The selection list contains all analytical fields and only discrete fields that are valid for temperature fields.

      Alternatively, you can click to create a new analytical field. (See Chapter 58, The Analytical Field toolset,” for more information.)

  4. In the Temperature field, enter the initial value of the fluid temperature.

  5. Click OK to save your data and to exit the editor.
