Question Regarding Temporal Interference Tutorial in Sim4Life

[abbytang]

Dear ZMT Team,

I am currently studying the Temporal Interference tutorial with the SAM Head model, as provided in the Sim4Life documentation (Tutorials/EMLF/LF_Multiport.html#temporal-interference-with-sam-head). I have followed the steps carefully up to the solver stage.

However, during the simulation run, I encountered the following warning:
Solid X_Electrode (Selected_Electrode): PEC - no edges associated with this material and thus it is disregarded.

Also, I’m not sure if the simulation problem affects the analysis. The E-field distribution doesn’t show up, but the tutorial shows it in the figure at the bottom.

Could you kindly advise if this warning affects the simulation output, and how I might resolve the issue or verify my results?

Thank you very much for your time and support.
