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.

 

Pre-requisite module - MATH1054.

Graduate Attributes

Graduate Attributes are the personal qualities, skills and understandings that University of Southampton students have the opportunity to develop. They include but extend beyond subject-specific knowledge of an academic discipline and its technical proficiencies. The Graduate Attributes are achieved through the successful attainment of the learning outcomes of the programmes, and successful engagement with the University’s co-curriculum e.g. the Graduate Passport.

A checklist for embedding the graduate attributes is available at: https://sharepoint.soton.ac.uk/sites/ese/quality_handbook/Handbook/Employability%20Statement.aspx

Cost Implications

 

 

  • A range of standard construction materials are provided to support the design projects within this module. However, students are encouraged to develop unique designs and choose alternative materials, the costs of which will be covered by the Faculty should they be deemed appropriate and clearly presented by a given cut-off date. The costs of additional materials and components identified after this date would be borne by the student group. (equipment)
  • Students are expected to cover the costs associated with the printing of drawings and graphic presentations. These are typically expected to be of the order of £50 per group (typically five students per group), also depending on the quality of printing chosen. Two CDs to submit computer codes to be covered by the each student. (printing-and-copying)
