Linear Transient Heat Transfer Analysis on a Piston

did you create your SPCD or DAREA loads in the constraints panel?

If yes, please check it you have created them in the correct load collector.

If not, use 'organize' to move them to the correct load collectors.

this tutorial from the help is almost what you need.

The only change is the imposed temperature that you want on the top surface.

You should use SPCD for it, not TEMP. It's just like your ambient temperature setup.

And don't forget that your SPCD value is multiplied by the values in your TABLED1.

In #7 data reference you can define type as TEMP and get the required result.
