Hello,
You have placed your custom components in a standard PLECS Circuit block. But you need to use the PLECS Library Block in the PLECS Extras category, as shown in the attached image. Place this block into a Simulink model, add your custom components, and save it. Then link to this model in the PLECS Preferences and it should appear in your library browser so that you can then drag it into any other model. Let me know if you get this to work, thanks!
