Finite Element Analysis

In the demo class for UG Mechanical and Production Engineering students on Finite Element Analysis (FEA), outline the course and provide a brief introduction to 1D elements, stiffness matrices, and their assembly and solving process. Here’s a structured plan for your demo class:

1. Introduction to Finite Element Analysis (FEA)

• Definition: Briefly explain that FEA is a numerical method for solving complex engineering problems, especially in solid mechanics, fluid dynamics, heat transfer, etc.
• Applications: Mention practical applications like stress analysis in automotive parts, thermal analysis in electronics, etc.
• Purpose of the Subject: State that the course will teach them how to model and solve engineering problems using FEA.

2. Overview of Course Content

Provide a brief outline of all the units in the course:

• Unit 1: Introduction to FEA
