T-junction with thermal equivalent circuit

Hello,

I'd like to understand and create a simple thermal model. I have thermal impedance specified from datasheet,

I create the thermal model with Foster network.

I'd like to know how can I attach the PowerLoss source to this thermal network? What conversion or block should I use to to feed this thermal network?

Consider a "Heat Flow Rate Source" or a "Controlled Heat Flow Rate Source". It can also be connected to the thermal port of any block that has a thermal port that outputs the power dissipated by that block.
