Request for Guidance on Current and Impedance Calculation in EPB + Petri Dish Model
-
I am currently working on an Electro Quasi Static simulation in Sim4Life Lite, where I am modeling an Electrode Planar Biocompatible (EPB) device placed inside a Petri dish filled with conductive solution.
The geometry is structured as follows:Petri Dish: cylindrical container filled with conductive solution.
Solution: conductive medium fully filling the dish.
Substrate: a thin planar silicone layer (3.5 mm x 2.5 mm x 0.1 mm) placed inside the solution.
Electrodes: two rectangular metallic electrodes (1.2 mm x 2 mm x 0.01 mm) embedded on the planar substrate, oriented towards the lesion area.
The electrodes are physically placed on the substrate and are not suspended in air.Configuration Variants:
The EPB is placed on the bottom of the Petri dish (electrodes in contact with the bottom).
The EPB is suspended in the solution (electrodes fully surrounded by the medium).
I have already successfully run the simulations and obtained the electric field and potential distributions.
In setting up the simulation, I used Extracted Faces by selecting the top faces of the electrodes and dragging them into the boundary conditions, instead of dragging the entire electrode object.However, I would like to know:
How can I calculate the total current absorbed by the electrodes in each of the two configurations (on the bottom vs. suspended)?
How can I compute the impedance of the electrodes in these scenarios using Sim4Life Lite?
Are there specific post-processing tools or port definitions that I should use?
Do I need to set up additional boundary conditions or use a particular solver output?
