thermal study on Radioss

I'm studying brake disc thermals for a college project. For now it's just a basic study to then put everything into practice. But when I analyze the temperature that the disk is, it seems that everything is 0 kelvin, even putting the initial temperature as 300 kelvin. Could someone correct and put the Model here for me to study it.

I took a quick look, you should model with bricks (since shells cannot capture a temperature gradient through their thickness), and your /HEAT/MAT cards are missing specific heat capacity values

In your existing model if I request /ANIM/NODA/TEMP, then I can see your temp of 300 (nodal temperatures), for bricks /ANIM/ELEM/TEMP would give temperature as well (though /ANIM/SHELL/TEMP is documented, I don't think it is applicable here, may be a documentation error?)

I changed a few things but it still didn't work
