Setting Local Mesh Sizes for Waveguide Port Faces

Refine the mesh locally at the waveguide port faces. The faces for the waveguide ports require a finer mesh to represent the highest mode that should be taken into account. The higher order modes are typically evanescent modes.

1. In the 3D view, select the three waveguide port faces.
2. From the right-click context menu, select Properties.
3. On the Modify Face dialog (Meshing tab), specify the following:
   1. Select the Local mesh size check box.
   2. Set the Mesh size to lambda/20.

4. Click OK to apply the properties and to close the dialog.

Note: The icon in the details tree indicate that a local mesh setting is applied.
