What to Do with Warnings in Electromagnetic Analysis

The selected mode doesn't propagate.
 This warning appears when a non-propagating mode is selected as an input in the 3D harmonic analysis.
Check the electromagnetic field and confirm that expected propagation modes are acquired. Enter "port electromagnetic analysis" on the [Search] tab of this help window. You will find documents related to the subject.

The possible causes of this warning are as follows:
・ Ports are not set properly. (Usually, two or more electrodes are required)
Action to take: Set up the ports again correctly. Tutorial and various examples will be of help.

- In the analysis of waveguides, the frequency is less than the cutoff frequency.
If results are as you expected, no actions are required.
