Specification

Aims

To provide students with a good understanding of the mathematical theory underpinning advanced computer based numerical modelling techniques. To investigate the application of various modelling techniques to Civil Engineering problems. To provide an insight into the process of developing conceptual and idealised models of Civil Engineering problems.

Learning outcomes



On successful completion of this course a student will be able to:

1. Critically evaluate and select appropriate modelling techniques for a given Civil Engineering problem.

2. Develop conceptual and idealised models of Civil Engineering problems.

3. Translate an idealised model into a computer model.

4. Solve the computer model using a range of software tools.

5. Test and validate solutions derived from computer models.
