Computing current between two electrodes

Hi everyone,
I've set up a basic model with two electrodes in a block of tissue, with one electrode having a fixed potential boundary condition and the other set as ground. Using the Electric Currents (EC) module, I can obtain the electric potential distribution within the volume, but was wondering how to obtain the actual current flowing between the electrodes?
It's my first time using COMSOL so any help would be appreciated, thanks!
Best wishes, Ryan

The current density is one of the available variables in the module you are using. The current at the electrode is computed as the line (if in 2D) or surface (in 3D) integral of the current density (derived values/integration/etc.). Good luck Andrea

Ah got it, thanks so much Andrea!
