CENV2026 Numerical Methods

Module Overview

This module provides an in depth coverage of key numerical methods to solve practical mathematical problems that occur throughout engineering. The module consists of two main parts: 1. The course demonstrates the use of numerical analysis as a powerful problem solving tool in engineering. The course encompasses Numerical Analysis, Regression Analysis, Taylor Series and Applications, Numerical Integration and Solutions to Ordinary Differential Equations, with applications to engineering problems through computational simulations using a commercial package, MATLAB. 2. The course also provides an introduction to the theory underlying the finite element (FE) method, with applications through computational simulations for a range of engineering problems using a commercially available general-purpose finite element package, ABAQUS. Computer lab exercises and assignments will give opportunity for students to analyse and solve a number of practical engineering problems.

Aims and Objectives
