Current Density Plot with EC physics
Hello,
I'm very new to comsol and was wondering if one is able to plot the electric current between two plates through a liquid (conductive) solution. I've been looking at the busbar example and see that in order to get the surface current plotted, the example adds a 3D Plot Group->adds a Surface-> Replaces the expression with the Electric Currents>current density norm (jh.normJ).
My question is: Is this same expression available when I'm using an EC stationary study?
Thanks!

Re: Current Density Plot with EC physics
Hi
the EC solves for V such that your conducting media has some current passing, but COMSOL will give you the current "density" so you need to define a spatial direction and length (an edge, or a Data Set Cut line) to get the current flow, to get the total current along a direction you need to integrate over some area (perpendicular to your edge / line)

Good luck
