I want to perform TACS (Trans-cranial Alternating Current Stimulation) with 2 electrode pairs, each at a slightly different frequency to create an envelope of the difference. I can not find something like that. The only thing that is possible is to use Electro Quasi-static LF Solver and have one frequency set.
Do you know how can I achieve this?
Thanks!
If Superposition principle applies to your problem you can perform two separate simulations with the desired frequencies while using the same grid and extract the field values so you can post process on your own.
Hello dstoupis,
I believe you aim to model the so-called temporal interference. The is a tool in Sim4Life for this called Max Modulation. You need two simulation with the same grid. Then you can multi-select the two fields in the Output View (each from one simulation) to have the Max Modulation button appear in the Ribbon.
Best, Habib
Sorry, to clarify, in order to set up the two different frequencies to model temporal interference, are we supposed to go into LF - Electro Quasi Static Simulation -> Setup -> Frequency? Or is this not the correct way to change the frequency?

Thank you @Habib! It was a simple selection of the two "Overall Fields" to have the "Max Modulation" tool show up! It helps a lot, since extracting the data and the processing it using Python to superimpose the fields and get the corresponding graphs, takes a lot of time.
