The 8th MCSul / VIII SEMENGO is a scientific event that received around 200 complete papers for oral presentation. The 8° MCSul / VIII SEMENGO took place on October 22, 23 and 24 at Federal University of Rio Grande (FURG), in Rio Grande City, Rio Grande do Sul State, Brazil. The MCSul (Southern Conference of Computational Modeling) is promoted by the Graduate Program in Computational Modeling (PPGMC) of FURG; being a multidisciplinary scientific congress which brings together researchers of Computation, Engineering, Physical, Mathematics and its several interfaces, by means the Computational Modeling, involving models, algorithms, tools and computational techniques for the solution and analysis of complex systems. The SEMENGO (Seminar and Workshop in Ocean Engineering) is promoted by the Graduate Program in Ocean Engineering (PPGEO) of FURG; being a forum which brings together researchers and practitioners of Ocean Engineering, Coastal and Port Civil Engineering, Naval Mechanical Engineering Naval and Renewable Energies, allowing the exchange of scientific and technical experiences. A RESM regular issue with special focus on Computational Modeling applied to Ocean Engineering Structures will be published from selected papers of The 8° MCSul / VIII SEMENGO.
