Hello Jorge Vilhena

The Fluid Solid Heat transfer in Explore mode was introduced in the latest 2022 R1 version.

Please note that the tutorial sues 2022 R1 version as mentioned in the video title.

I would recommend you download the latest version from here to run Fluid solid heat transfer simulation in explore mode. 

If you are using the older version, you can try the same simulation in Refine mode.
