Using the CFIE Method For Closed PEC Regions

When solving an enclosed perfectly conducting metallic region using the MLFMM, the CFIE method is used to obtain results with faster convergence using less memory.

  1. Ensure the multilevel fast multipole method (MLFMM) solver is activated for the model.
  2. Select the face of the enclosed volume in the in the 3D view or in the details tree.
  3. In the details tree, from the right-click context menu, select Properties.
  4. On the Face properties dialog, click the Solution tab.
  5. From the Integral equation drop-down list, select Combined field1.
  6. Click OK to save the face properties and to close the dialog.
