Finite Element (FE) Method and Heat Source Model in Conduction Mode Welding Processes

This course covers the intricate aspects of finite element modeling of fluid flow problems, with a special focus on heat conduction problems. For instance, students learn about the development of a finite element-based model, the significance of material flow, and the governing equation of fluid flow. The course also delves into the continuity equation, momentum equation, and energy conservation equation. It introduces the concept of a control volume and the different phenomena associated with it. The course also covers the concept of the natural coordinate system in three-dimensional problems, explaining how to map the local coordinate system to the global coordinate system using a brick element as an example. The course concludes with a comprehensive discussion on mathematical modeling in welding processes, focusing on the heat source model in conduction mode welding.
