Magnitude Options

This is a grounding load. The magnitude is always zero.

Applying a Voltage (Ground) Boundary Condition

To apply a Voltage (Ground):

  1. Select the Voltage (Ground) option from the Electric group on the Environment Context tab. Alternatively, right-click the Environment tree object or in the Geometry window and select Insert>Voltage (Ground).

  2. Define the Scoping Method as either Geometry Selection, Named Selection, or Voltage Coupling and then specify the geometry.

Details Pane Properties

The selections available in the Details pane are described below.

CategoryProperty/Options/Description
Scope

Scoping Method: Options include:

  • Geometry Selection (default): Default setting, indicating that the boundary condition is applied to a geometry or geometries, which are chosen using a graphical selection tool.

    • Geometry: Visible when the Scoping Method is set to Geometry Selection. Displays the type of geometry (Body, Face, etc.) and the number of geometric entities (for example: 1 Body, 2 Edges) to which the boundary has been applied using the selection tools.

  • Named Selection: Indicates that the geometry selection is defined by a Named Selection.

    • Named Selection: Visible when the Scoping Method is set to Named Selection. This field provides a drop-down list of available user–defined Named Selections.

  • Voltage Coupling: This option is only available for Coupled Field Harmonic and Coupled Field Modal analyses. It indicates that the geometry selection is defined by a Voltage Coupling .

    • Voltage Coupling: Visible when the Scoping Method is set to Voltage Coupling. This field provides a drop-down list of available user-defined Voltage Coupling objects.

Definition

Type: Read-only field that displays boundary condition type - Voltage (Ground).

Magnitude: This is a grounding load. The Magnitude value is always zero.

Suppressed: Include (No - default) or exclude (Yes) the boundary condition.

Mechanical APDL References and Notes

The following Mechanical APDL commands, element types, and considerations are applicable for this boundary condition.

  • Voltage (Ground) is applied using the D command.

  • Magnitude is set to zero volts.
