Inquiry Regarding TI Simulation Setup in Sim4Life

[abbytang]

Dear ZMT team,

I am a new user of Sim4Life and currently exploring TI simulations. While setting up the simulation, I encountered a few questions and would appreciate your guidance.

1.Electrode Frequency Configuration

Is the frequency setting for TI stimulation configured exclusively through the GUI path Setup > Frequency?

If scripting is preferred, is the following Python code snippet correct for setting the frequency to 2 kHz?

quasi_static_setup_settings.Frequency = 2000.0 * units.Hz

2.Current Amplitude Setup (2 mA)

To achieve a total current of 2 mA through a circular electrode (radius = 4 mm), I calculated the current density as 1/ΠR2 mA/mm² and applied it via Boundary Conditions > Constant Flux.

However, the Analysis > Max Modulation output appears empty. Could you confirm if this approach is correct or suggest alternative methods to define the current?

3. Result Export for TI Interference

How can I export the TI interference results (e.g., electric field magnitude) for all voxels or a specific point in the brain? Are there predefined scripts or GUI options for this purpose?

I apologize if these questions are basic, but your clarification would greatly help my learning process. Thank you for your time and support.
