DURSTEWITZ, C. Barrios et al. Simulation and Modelling of Cathodic Protection Systems by the Finite Elements and the Boundary Elements Methods. Port. Electrochim. Acta [online]. 2005, vol.23, n.1, pp.123-137. ISSN 0872-1904.

The development of mathematical models and the simulation of cathodic protection systems applied to buried tubing are presented. The solution of partial differential equations is obtained by numerical methods like finite elements and boundary elements. The purpose is developing a quantitative method of potential distribution prediction on the surface of the buried structure, covering aspects like selection of materials, geometric configuration and design of the system. As verification problems were used the problem of the square tank, and the problem of the cylindrical container. Finally two cases of buried structures are presented.
