This multiphysics modeling functionality is available for phenomena involved in problems like stress corrosion cracking (SCC) and oxide jacking in concrete. With the underlying capabilities of the COMSOL Multiphysics ® platform, the Corrosion Module can be combined with other add-on products to model coupled phenomena, such as heat transfer and structural mechanics. The electrolyte can be described as a thin layer of moisture, a porous material, or a liquid electrolyte. The module makes it easy to define relevant boundary conditions, surface reactions, and bulk electrolyte conditions. These corrosion processes stem from similar types of electrochemical phenomena for which the transport and balance of both charge and mass must be considered. It can also be used to model sweet and sour corrosion in oil and gas systems, corrosion in reinforced concrete, and corrosion from stray currents. The Corrosion Module can be used to model a wide variety of corrosion processes, such as galvanic, pitting, crevice, atmospheric, and general corrosion. The transport and reaction processes that describe corrosion and corrosion protection systems can be modeled in 1D, 2D, and 3D using the finite element method (FEM) and boundary element method (BEM). The module includes a thermodynamic database with electrode potentials and a selection of kinetic expressions for the most common redox reactions at these surfaces. The Corrosion Module also includes capabilities for describing in detail the charge transfer reactions that are responsible for corrosion occurring at electrolyte–metal surfaces. The modeling process is streamlined by the software's capacity to describe the transport processes in an electrolyte, including the transport of ions and neutral species as well as the balance of current in metal structures. The Corrosion Module, an add-on to COMSOL Multiphysics ®, enables engineers and scientists to effectively model corrosion processes and protection systems in an intuitive user interface. Modeling and simulation are powerful tools for understanding corrosion and designing and optimizing corrosion protection systems. Model Corrosion Processes and Corrosion Protection Systems
