Defining Symmetry

Translate the model to set symmetry to use model symmetry and reduce computational costs.

Symmetry planes are only possible at the global origin. Center the geometry across the X, Y and Z planes.
  1. In the model tree, select Union2.
  2. On the Transform tab, in the Transform group, click the  Translate icon.
  3. On the Translate dialog enter the From and To coordinates.
    • From: (0, 0, wg_h/2).
    • To: (0, 0, 0).

    Note: This translation will move the structure down so that it is symmetrical around the XY plane.
  4. Click OK to close the dialog.

The model has magnetic symmetry across the XZ plane and electric symmetry across the XY plane. The computational resources can be reduced by allowing the solution kernel to utilise symmetry. Note that this step is optional and you are encouraged to remove symmetry later to compare the differences in resources.

  1. On the 3D View context tab, on the Display options tab, in the Solver display group, click the  Symmetry icon.
  2. Specify the following symmetry:
    • Y=0 plane: Magnetic symmetry
    • Z=0 plane: Electric symmetry

Optional: Hide the symmetry.

  1. On the 3D View contextual tabs set, on the Display tab, in the Method display group, click the  Symmetry icon.
