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.
-
From the Flow ribbon, Domain tools, click Sources > Heat.
Figure 1. - Select solids.
- In the microdialog, select a definition and a type.
-
Define the heat source.
Option Method Constant Enter a heat source value. Linear, Cubic Spline, Piecewise Linear - Click
.
- In the heat source dialog, select a variable from the Varying motion basis drop-down menu.
- Use the table and plot area to input function data.
User Function - Click
.
- In the heat source dialog, enter a function expression.
- Select an argument from the drop-down menu.
- Use the table to input data.
- Click
-
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.
- Click
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.
-
From the Flow ribbon, Domain tools, click Sources > Momentum.
Figure 2. - Select solids.
-
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 - Click
.
- In the momentum source dialog, define the X axis using the Curve fit variable drop-down menu.
- 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 - Click
.
- In the momentum source dialog, enter a function expression.
- Select an argument from the drop-down menu.
- Use the table to input data.
