Modifying the CFIE Factor

Activate the combined field integral equation (CFIE) method for the model and specify the factor for the linear combination of the magnetic field integral equation (MFIE) method and the electric field integral equation (EFIE) method.

  1. On the Solve/Run tab, in the Solution settings group, click the  Solver settings icon.
  2. On the Solver settings dialog, click the Advanced tab.
  3. Under Integral equation settings, select the CFIE factor check box and in the edit field, enter a value for the CFIE factor.


    Figure 1. The Solver settings dialog (Advanced tab).
    • CFIE factor = 0
      A pure magnetic field integral equation (MFIE) solution.
    • CFIE factor = 1
      A pure electric field integral equation (EFIE) solution.
      Note: The EFIE is the default integral equation method.
    • 0 < CFIE factor < 1
      A combination of the MFIE method and the EFIE method. This is known as the combined field integral equation (CFIE) method.
