New and Updated Models in Version 5.2a Monopile with Dissolving Sacrificial Anodes Tutorial The new Monopile tutorial demonstrates how the Sacrificial Edge Anode node can be used in cathodic protection simulations. Updated Models • The Cathodic Protection of Steel in Reinforced Concrete model has been updated to use the new Primary Condition (Thermodynamic Equilibrium) electrode kinetics. • The Diffuse Double Layer model has been updated to use the new Nernst-Planck-Poisson Equations multiphysics interface.
