Where can i find the demo "Voltage regulator with TL431", it is a demo plecs about the flyback power supply

hi all,
Currently i am working on a flyback SMPS design, from below link, there is a demo for this kind of design.

I try to find this demo in the standalone (version 4.8.9), but I cannot find this demo.
Can anyone share this demo or guide me how to find it anywhere else?
Thanks a lot in advance.

This demo is not included in the standard PLECS installation. However, you can easily download the necessary files and documentation using the link which you provided.

thanks for the reminding. I realize that there is a download link at the bottom of the page.

Hi, this is an old application note where the model files are not included in PLECS directly (as a regular demo model), but rather are available just on our website. On the webpage your reference, there is a section to download the files.
