TL;DR
The finite element method (FEM) is a numerical technique used to perform finite element analysis (FEA) of any given physical phenomenon.
Practically every Physics problem that needs solving has to be solved by numerical methods in the modern tech world. Approximating solutions to solve partial differential equations seems a useful approach when solving difficult problems on complex geometries.
FEM is a way to find approximate solutions to these ‘impossible to solve’ PDEs with numerically modeled equations, which can be solved using numerical methods. Solutions to numerical modeled equations approximate the solutions of PDEs.

Subjects studied
- ME 4709 Computer Aided Design
Design prodess does not stop after iterating and arriving at a shape concept. The design finalized is tested and analyzed in solvers which solve partial differentiel equations to arrive at solutions that pertain to the problem. Mostly, these equations are equations of Physics to solve displacement, stress – strains and forces in case of structural problems, and flow rates + relevant stuff in case of CFD (Computational Fluid Dynamics).
The final project required us to code the equations in ANSYS APDL, to find the approximate solutions
