This module covers two areas of
computational engineering : Computational Fluid Dynamics, or CFD, and
Finite Element analysis applied to structures and materials. Although
this describes the course, it is worth sorting out the terminology. The
course covers computational approaches to continuum
mechanics problems. However there are three basic approaches in use
:
Most commercially available CFD codes (such as Fluent, STARCD, and CFX) are based on the Finite Volume method. The aim of the module is to provide the student with the necessary tools to make critical use of computational methods for solving engineering problems. Commercial codes are available which represent thousands of manhours of work developing these methods, and so it is seldom necessary to write a CFD code from scratch. However it is necessary to understand the methods being used in order to utilise them to get the right answer. Wrong answers are very easy to get from a CFD code though. FD Methods:Lecture slides can be downloaded
(lecture notes also available for 1, 2, 3, 4) CFD:The course includes a set of 4 lectures on the basics of CFD. The lecture slides can be downloaded (lectures 1, 2, 3, 4) or as notes (notes 1, 2, 3, 4). Alternatively a full text version of the lectures is also available:
A short exercise using the commercial code Fluent is provided to familiarise the student with the basics of operation. The student then undertakes a number of short `miniprojects', using CFD to investigate engineering problems. FV transport spreadsheet here. (a more sophisticated version is also available here).
