Create an Electrical Source

If you are solving a problem that includes electric current, you may specify the electrical source at the boundary between two conducting solids or on the outer boundary of a conducting solid.

The possible types of an electrical condition are DС Current, and DС Voltage.

Restrictions and Limitations

This feature is available for the Electronics Cooling module users only.

Prerequisites

  • The Conduction option must be enabled on the Analysis Type tab of the General Settings or Wizard dialog.

Procedure

  1. Open the Electrical Source  dialog:

    • On the ribbon, click Flow Simulation > Insert > Conditions > Electrical Source.

    • In the menu, select Tools > Flow Simulation > Insert > Electrical Source.

    • In the Flow Simulation Analysis tree, right-click the Electrical Sources item and select Insert Electrical Source.

  2. In the Type list select the desired electrical source type:

    • DC Current. Electric direct current normal to the surface.

    • DC Voltage. Electric direct potential on the surface.

  3. Under Selection, select faces on which you intend to specify the electrical source (see “Selection List” for details).

    • If the DC Current or DC Voltage is selected, select faces in the graphics area or components in the flyout FeatureManager design tree. The selected faces and components appear in the Faces to Apply the Electrical Source list.

  4. If the selected type of electrical condition is DC Current, specify the following parameters under Value:

    • In or Out direction.

    • Current  value. Click Dependency  to the right of the parameter value input box if you want to specify time-dependent values (see “Dependency” for details).

    Note:

    You can specify either positive or negative value of the electric current. Also you can specify a sign-changing current by using Dependency (see “Dependency” for details).

  5. Under Goals you can select goals to associate with the electrical source.

    Those goals are created together with the electrical source and remain connected with the same geometry.

  6. When creating a new electrical condition, in the Name Template box you can specify a template for its name.

    The default template is the <Type> placeholder, followed by <Number>, where <Type> is the electrical source type and <Number> is the sequential number of the electrical condition in the Flow Simulation Analysis tree. When electrical source is created, <Type> is replaced by the source type (for instance, “DC Current”) and <Number> is replaced by the sequential number of the electrical source (for example, if the electrical source named “DC Current 1” already exists, the new electrical source will be named “DC Current 2” and so on). You can combine these standard elements in any order and add any appropriate characters to the template. To add a new standard element to the template, click the Type  or Number  button.

  7. Click OK .

    -or-

    Click Keep Visible  before clicking OK  to keep the dialog open and define more electrical sources.

Results

The new Electrical Source item appears in the Flow Simulation Analysis tree.

To edit the definition of an Electrical Source, in the Flow Simulation Analysis tree, double-click the Electrical Source item, or right-click the item and select Edit Definition.

Also you can use a callout in the graphics area to edit definition of an Electrical Source (see “Feature Callout” for details).
