Finite Element Analysis: techniques involve dividing a complex object into smaller, simpler parts (elements) to simulate and predict its behavior under various conditions like stress, heat, and fluid flow. The main stages of FEA are preprocessing (creating the model and mesh), solution (solving the mathematical equations), and post-processing (analyzing the results)

The process:

1. Preprocessing 
   • Define Geometry
   • Assign Materials
   • Apply contacts and loads
   • Mesh Generations

2. The solver assembles and solves a huge system of equations (Kx = F)

   • K = stiffness matrix

   • x = displacements

   • F = forces/load vector

3. Post Processing (visualize results)
