Learning Outcomes:

At the completion of the module, the students should be able to:

1. Demonstrate knowledge and understanding of basic concepts of continuum, field theory, and conservation and constitutive laws.

2. Formulate and solve simple Continuum Mechanics problems, i.e. problems involving field theory, stresses, deformation and flow, conservation and constitutive laws.

3. Demonstrate understanding of fundamental basics of FV discretisation procedure; Define and set-up within the FV framework a variety of steady and unsteady continuum mechanics problems.

4. Demonstrate understanding of fundamental basics of FE discretisation procedure; Define and set-up within the FE framework a variety of steady and unsteady continuum mechanics problems.

5. Identify main differences between FV and FV methods, their advantages and disadvantages, and hence decide which of the method will best suit a particular problem.

6. Present and justify the main assumptions and findings in formulating and solving a CCM problem.
