I want to run thermal analysis using mechanical feature coupled with HFSS in AEDT. I first run HFSS and use EM loss as a thermal excitation to import EM loss data from HFSS to Thermal module. My model consists of biological tissues, which vary from 37C-40C and electronics, which have a temperature of 24C (also an ambient temp - room temp).

I have questions regarding the boundaries.

1. My model has multiple layer embedded in each other, mimicking a rat head . I use convection as a boundary for the outermost layer because all faces of this layer are in contact with air. I only know this layer's convection coefficient. Should I also assign convection for the inner layers?
2. Is there a way to assign an initial temperature for the components? I used temperature as a boundary for the inner layers, but it gave me overlapping issues with EMloss. But using temperature (aka assigning a fixed temp) might not be correct because I expect the temperature to rise as a result of the simulation.
3. I included the result of my first attempt below. I think the the temperature map is incorrect. I expected the temperature at the device's site to be 41-42C (based on literature of my project) , and the ambient temp should remain at 24C. The temperature inside the tissues is also too high.

Would you please take a look at my questions?
Thank you.
