Hi
I need to obtain the electric current density field in a medium attributed to a pair of source and sink electrodes with known current. what physic should I choose and what boundary conditions should I determine?
Thank you

Hi

I would say EC (electric current) you solve for V and the current comes from the material conductivity.

as usual in COMSOL you need your geometry, your material properties, the EC physics, a GND and a terminal (if you have a voltage or current average value to define on a boundary, if you have already a voltage or current field, you need to use the Electric Potential or current source BC, and off you go ... ;)

Good luck
