Using the CFIE For Closed PEC Regions
When solving an enclosed perfectly conducting metallic region using the MLFMM, the CFIE can be used to improve the iterative solver convergence.
- Ensure the multilevel fast multipole method (MLFMM) solver is activated for the model.
- Select the faces 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 Modify Face dialog, click the Solution tab.
- From the Integral equation drop-down list, select Combined field1.
- Click OK to save the face properties and to close the dialog.
