Hi,
We have an impressed current cathodic protection of a steel structure in seawater.
I found that the main electrical resistance exists in the vicinity of the anode. Driving voltage is +50 V at anode, cathode voltage is 0 V.
Can anyone give a hint how to model an circular anode in FE software? - the goal is to calculate the anode resistance to far ground.
Can it be modelled in 2-D with reasonable result, or is 3-D necessary?
For simple anode shapes, it seems to be possible to derive mathematical expressions.
