By Carlos Eduardo Fontes, September 29, 2021 FEA or CFD: in which physics to deepen studies in computer simulation? Education & Research Today, we are moving towards a multiphysics universe, where computational tools provide the possibility to assess globally and at the same time the problems that these physics involve. This is made possible by using computers to replicate real-life processes, phenomena, or a system through computer simulation. In times where companies seek scalable results, agile adaptation, and innovation, simulation becomes an essential tool. Simulations of different physics can complement each other according to the industry that will be explored. CFD – Computational Fluid Dynamics Computational Fluid Dynamics (CFD) is the area of knowledge that deals with the numerical simulation of fluid flow, heat transfer, and related phenomena such as chemical reactions, combustion, and aeroacoustics. CFD originated from the combination of two disciplines: fluid mechanics and numerical calculus. A specialization in this area will enable the fluid dynamics specialist to use the knowledge from the conceptual phase of a project, helping to determine the feasibility and best solution in a product, to the production stage, allowing them to represent various scenarios. FEA – Finite Element Structural Analysis Structural analysis using the finite element method works with thermodynamic and structural simulations, making it possible to predict the behavior and performance of complex products more realistically. The method proposes that the infinite number of unknown variables be replaced by a limited number of elements of well-defined behavior. After designing the model and generating the mesh with the elements described above, the simulation is configured and the first tests are performed, techniques that a specialist in structural analysis masters in theory and practice. The valorization of computer simulation in the market Choosing any of the two physics, the engineer who masters computational simulation opens up a very broad field of work. A certification in this area is valued in the market, as industries increasingly demand the application of this technology. Thus, having a specialization in computational fluid dynamics or structural analysis by finite elements in the curriculum is a very promising path, both for experienced professionals and for those starting a career in engineering. Carlos Eduardo Fontes Coordinator of the Esss Institute and ESSS Academic Area Chemical Engineer graduated at UFRJ, holds a Masters and a PhD in Chemical Engineering from the same institution. Currently he is the ESSS Institute and ESSS Academic Area Coordinator, working throughout Latin America. He has experience in fluid dynamic simulations (CFD), with emphasis in reactive and multiphase flows. Other areas of expertise are the application of fluid dynamic simulations in risk analysis and the development of new processes in the oil/gas/ethanol area.
