Basics of Finite Element Analysis

Finite Element Analysis (FEA) is an indispensable tool for modern engineers, allowing us to simulate and analyze how physical structures react to real-world forces, heat, and other physical effects. This text-based course introduces you to the core mathematical and physical principles of FEA without requiring any prior simulation experience. You will transition from understanding basic physical systems to formulating and solving complex engineering problems systematically. What you will learn: Understand the foundational mathematics behind FEA, including weighted residual methods and variational formulations; Apply 1D spring, bar, and beam elements to model structural behavior under load; Develop the governing equations for 2D and 3D structural analysis; Practice solving thermal and fluid flow problems using finite element approximations; Configure boundary conditions and mesh refinement strategies to ensure simulation accuracy. The course begins with essential terminology, basic definitions, and the underlying mathematical frameworks before guiding you step-by-step through practical engineering applications and modern modeling workflows. This course is designed for engineering students, product designers, and professionals looking to build a strong theoretical and practical foundation in engineering simulation.
