No, Have you used it?

I've played around with it. I think the biggest problem is that it lacks a database for materials so you need to enter all the parameters by yourself. Specific heat, density, thermal conductivity, to name a few. You'll spend a lot of time with search engines and then another lot of time to enter the data. For aluminium you find the data readily in e.g. Wolfram Alpha, but try the same for FR4? How do you model a "Silpad" if you only know its total thermal resistance in K/W ?

The next thing you need to figure out is how your model should look like. Then, the editor to capture your design is also quite cumbersome to use, I guess the best way is to sketch out the model on paper and then enter numerically.

So, it's probably doable, but it's in no way easy and quite disruptive to an iterative workflow.

I have made a tool to simulate the temperature of a PCB.
It may give you some numerical results. You can find it at https://leiterplatte.jimdo.com/thermal-pcb-sim/
Kind regards
