Introduction to Electromagnetism
That module extended FEM beyond mechanics and heat transfer into the field of electromagnetics. This showed how the same numerical principles can be applied to simulate electric and magnetic fields, giving a broader view of multiphysics applications
The assignments focused on:
Electrostatics: solving for electric potential and field distribution in dielectric media with applied voltages and boundary conditions.
Magnetostatics: analyzing magnetic fields generated by current-carrying conductors and evaluating field strength around different geometries.
Coupled problems: studying how electromagnetic fields interact with materials, highlighting applications such as inductors, shielding, and transformers.
FEM formulation: deriving and assembling system matrices based on Maxwell’s equations, and comparing numerical results with analytical field solutions.
What stood out in this module was how quickly the scope of FEM expands once the governing physics are changed. The workflow of meshing, applying boundary conditions, and assembling equations remained the same, but the underlying phenomena required a completely different interpretation of results
This module provided a first step into multiphysics simulations, demonstrating that FEM is a unifying framework across disciplines. It emphasized the versatility of the method — whether analyzing stresses, temperatures, or electromagnetic fields, the same principles can be applied to gain insight into complex engineering problems
