Create Sources

Use the Sources tools to specify a collection of body forces (momentum or heat) within solid bodies.

Create Heat Sources

Use the Sources: Heat tool to define heat sources per unit volume or per unit mass for the energy equation.

  1. From the Flow ribbon, Domain tools, click Sources > Heat.


    Figure 1.
  2. Select solids.
  3. In the microdialog, select a definition and a type.
  4. Define the heat source.
    Option Method
    Constant Enter a heat source value.
    Linear, Cubic Spline, Piecewise Linear
    1. Click .
    2. In the heat source dialog, select a variable from the Varying motion basis drop-down menu.
    3. Use the table and plot area to input function data.
    User Function
    1. Click .
    2. In the heat source dialog, enter a function expression.
    3. Select an argument from the drop-down menu.
    4. Use the table to input data.
  5. From the guide bar, execute the command in the following ways:
    • Click to confirm your selection and remain in the tool.

      This allows you to continue creating instances and helps you visualize and edit instances with the legend.

    • Click to confirm your selection and exit the tool.

Create Momentum Sources

Use the Sources: Momentum tool to set up body forces applied to the momentum equation.

You can use this tool to define a body force locally for any solid body, apart from global gravity.

  1. From the Flow ribbon, Domain tools, click Sources > Momentum.


    Figure 2.
  2. Select solids.
  3. In the microdialog, select a type and define the momentum source.
    Option Method
    Constant Enter values for the components of the momentum source.
    Linear and Cubic Spline
    1. Click .
    2. In the momentum source dialog, define the X axis using the Curve fit variable drop-down menu.
    3. Use the table and plot area to input data.
    Tip: Click the X-source, Y-source, and Z-source options beneath the plot to toggle their visibility.
    User Function
    1. Click .
    2. In the momentum source dialog, enter a function expression.
    3. Select an argument from the drop-down menu.
    4. Use the table to input data.
  4. From the guide bar, execute the command in the following ways:
    • Click to confirm your selection and remain in the tool.

      This allows you to continue creating instances and helps you visualize and edit instances with the legend.

    • Click to confirm your selection and exit the tool.
