Dear All,
I have a 3D electric current model of an electrode in a medium, where the electrode is modelled as a thin disk. I would like to model this electrode as having non-uniform current density on its surface, which is determined by the radial distance from the centre of electrode.
,where 
is a constant value derived from the total current, 
is the radial distance and 
is the radius of the electrode.
I think the 'Terminal' boundary condition comes close to this, but is there any way to control the distribution of the current density so it follows this equation exactly?
