Current source for EM LF solver - How to correctly define a plane for flux evaluation

[oeddaoui]

Hi,

I followed the guide at https://forum.zmt.swiss/topic/24/compute-the-total-current-flowing-between-two-electrodes-in-an-electro-quasistatic-lf-simulation

I'm just not sure how to define a valid plane to calculate the current injected from my electrodes (when assigned arbitrary +1V and -1V respectively).

From what I understood, the plane must be placed between the electrodes, but in my case, the electrodes are not facing each other. Here is what I tried :

Is it a valid plane to calculate current injected from each electrode?

Also, extra question: let's say I have more than 2 electrodes stimulating, how should I define the plane? or planes?
