Setting Eddy Effects and Displacement Current

(Eddy Current and/or Transient Solvers)

For both eddy current and transient solvers, you may need to specify the following additional setting:

The behavior of eddy currents and the AC magnetic field in conductors. When you activate the Eddy Effect setting, the solver computes the induced eddy currents.

For 3D eddy current solvers only, you may need to specify the following additional setting:

The Displacement Current on the objects in the model.

Typically, background objects are excluded from eddy and displacement current settings.

To set eddy effects:

Select the elements of the geometry on which you want to apply the excitation.
Click Maxwell > Excitations > Set Eddy Effects.

The Set Eddy Effect dialog box appears.

For each object in the list, select or clear the check boxes for Eddy Effect and Displacement Current (3D Eddy Current T-W solver). When selecting multiple entries, the changes are synchronized for all selected rows.

Note: Multi-select is supported by holding the Ctrl or Shift key while clicking.

Click the Select Object By Name button to enter the name of a specific object for selection.
Optionally, click the Use suggested values button to set the Eddy Effects for all elements recommended by Maxwell 3D.
Click OK.

The Deselect All button will deselect all selected objects in the list.

Displacement Current for the 3D Eddy Current A-F

For the 3D Eddy Current A-F solver, the displacement current effect is set for the whole domain rather than for each object. As a consequence, the number of unknowns will increase and the simulation may require more memory and more simulation time.

To enable the displacement current effect:

From the Project Manager tree, right-click Excitations and select Set Eddy Effects.
Enable the Displacement Current check box.
