Modifying the Integral Equation Method
When using either the MoM or the MLFMM, you can specify the integral equation method to be applied to a face to obtain either faster iterative convergence or higher numerical accuracy.
- If the model is solved using the multilevel fast multipole method (MLFMM) activate the MLFMM.
- Select the face of the enclosed volume in the in the 3D view or in the details tree.
-
In the details tree, from the right-click context menu, select Properties.
- On the Face properties dialog, click the Solution tab.
-
From the Integral equation
drop-down list, select one of the following options.
-
- Combined field
-
Solve the model using a combination of the electric field integral equation (EFIE) and magnetic field integral equation (MFIE) methods. This is known as the combined field integral equation (CFIE) method.
-
- Electric field
- Solve the model using the electric field integral equation (EFIE) method.
-
- Magnetic field
- Solve the model using the magnetic field integral equation (MFIE) method.
Note: The electric field integral equation (EFIE) is the default method and is valid for general open geometries. -
- Click OK to save the face properties and to close the dialog.
