Thermal simulation for temporal interference stimulation

[tbone]

Hello,

I was wondering if anyone could help me with the thermal simulation for TIS.
The paper from IT'IS was the reference that I was using:
Recommendations for the Safe Application of Temporal Interference Stimulation in the Human Brain Part II: Biophysics, Dosimetry, and Safety Recommendations (https://doi.org/10.1002/bem.22536)

Do I use the Stationary Thermal simulation linked to one of the Electro Ohmic Quasi-Static simulations for the electrode pairs? Or according to the paper, should I use the coherent/incoherent superposition of the SAR values as the link to the thermal simulations? In the latter case, I am not able to link the 'SAR-Field Combiner' to the thermal simulation.

Thank you for your time!
