- Development of a Simulation Tool for Electromagnetism EducationPublication . Auwarter, Bianca; Brandão, Diego; Ferreira, Ângela P.The widespread adoption in the educational system of information and communications technologies allows the use of interactive simulations, able to support a meaningful insight into the fundamental laws and concepts of electromagnetic theory, which, in a classical approach, would require a vector calculus background and three-dimensional geometrical resourcefulness, typically not maturated by the students in undergraduate engineering programmes. The use of simulation tools based on finite element analysis can facilitate the learning process by allowing users to create and/or exploit visual and more accurate models. ONELAB (Open Numerical Engineering LABoratory) is a simulation platform that integrates severalmodelling tools, including Gmsh, a three-dimensionalmesh modelling software. This simulation tool is able to provide interaction, accuracy, and visual interpretations of classical problems using the fundamental laws of electromagnetism. The application with the basic laws of electromagnetism has been developed to run on mobile devices, besides desktops, to improve its ease of access and dissemination.
- A finite element based tool to support the understanding of electromagnetism conceptsPublication . Ferreira, Ângela P.; Auwarter, BiancaA significant pedagogical innovation in teaching and learning Electromagnetics in undergraduate engineering programmes is the resource to simulations, preferably interactive. A classical approach would require a vector calculus background and three-dimensional geometrical resourcefulness, typically not maturated by undergraduate students. On the other hand, interactive simulations are able to support a meaningful visual insight into the fundamental laws and concepts of electromagnetic theory. This work describes an educational tool which relies in an open source graphical user interface to finite element software, able to provide interaction, accuracy and visual interpretations of the Electromagnetics fundamental laws and classical problems, able to hasten the students’ understanding, by lessening the abstract nature of vector fields, level curves and gradient fields. This tool is to be further developed to gather a set of vast examples and typical problems, able to support a web-based training platform.
