The effect of electromagnetic field on the temperature of human tissues

I am now doing research on the influence of radio frequency electric field on human body temperature. Just now comsol switched to using SIM4Life, I hope someone can help me to use this software. What steps do I need to follow to use the model? Whether the conductivity parameters of the tissue model can be set freely according to different RF frequencies. I hope to know you and learn from you. I am currently a doctoral student in a Chinese university.
