Learning, Teaching and Assessment (LTA) Approach:
Learning & teaching methods including their alignment to LOs
The objective is to provide the learner with both the an understanding of the background theory to computer simulation of polymer processes and also practical skills in modelling and analysing the injection moulding process using the latest commercial software as well as the important interpretation of results. This will be achieved through a combination of lectures, and a series of progressively more complex computer based exercises which will be both formative and at times summative.

Embedding of employability/ PDP/ scholarship skills
There is always a strong demand for graduates who have specific high level skills in CAD and CAE however the supply of graduates with skills in FEA analysis of plastics moulding (e.g., Moldflow) is far short of global demand. Such graduates from Napier University have joined major OEM, e.g. Nissan and Philips as well as moulders such as Rosti and gone on to take up very relevant positions including placements in Germany and China.

Assessment (formative and summative)
A series of formative computer based exercises with immediate feedback will lead to two assessed exercises in weeks 5 and 10. The final 2 assessments will be carried out under supervised assessment conditions in a single 6-hour period during weeks 14 or 15. This format of a fixed time exercise has proved very successful over the years in separate the very best students

Research/ teaching linkages
The module leader has almost 20 years experience of using Moldflow software on an academic and occasionally consultancy basis. He has supervised many undergraduate and masters projects in this area and contributed papers to user group meetings. Case studies from past student projects and Alumni, as well as examples consultancy and other Moldflow users will be used to illustrate the application of the technology.

Formative Assessment:
The University is currently undertaking work to improve the quality of information provided on methods of assessment and feedback. Please refer to the section on Learning and Teaching Approaches above for further information about this module’s learning, teaching and assessment practices, including formative and summative approaches.

Description of module content:

This specialist module explains the basic background theory relating to computer simulation of polymer conversion processes involving heat and mass transfer. The content includes:
Materials data (thermal diffusivity, specific heat, viscosity, no-flow temperature, PVT and shrinkage);
Finite element and difference methods; boundary element methods; analytical and numerical solutions;
Use of commercial flow, cooling and packing analysis software packages (Moldflow Plastics Insight).

Learning Outcomes for module:

On completion of this module you will be able to:
LO1: explain databases and models defining material with thermal and rheological behaviour;
LO2: produce a computer package, using Excel or similar spreadsheet, to analyse transient heat transfer
and non-Newtonian flow in injection moulding simulations of simple geometries;
LO3: apply Moldflow Plastics Insight (MPI) software to analyse flow, cooling and packing in injection
moulding;
LO4: interpret the results of FEA flow and packing analysis to make informed decisions on product and
mould design, and/or process optimisation.
