Need some insight into modeling electroforming

I have reached the point, that my model is working to some degree, but I am not really sure, that I have been doing things correctly.
I created a 2D model with rotational symmetry, defined an anode and a kathode via an electrode surface node, use the deformed geometry functionality and model time dependent.
I use a user defined function, created from measurements, for the electrode kinetics in the electrode reaction subnode.
The data file contains a column for potential and one for the current density. When using the function, which potential should I use as an argument, when modeling the electrodeposition in galvanostatic control (constant current)? I chose phil from the initial values node.
From the data file I derive an equilibrium potential of -0,32... V. I assume that this is the value I have to enter for E_eq (for anode and kathode?).
If I remember correctly, when choosing total current or average current density, there is a potential value that can be changed. What is it for?
