In the first part of this research work a new version of the cooling simulation software was constructed by changing the old convection module, which used the commercial software package POLYFLOW, to a new version using an alternative code developed in the Centre for Polymer Processing at the University of Wales Swansea, called Fantazt. This change introduced a large number of modifications in order for the new convection module to work in harmony with the rest of the program. Also many improvements have taken place in the new version, with respect to the computational time and the functionality of the software. The new version had to be tested on a large variety of profiles and be able to reproduce results identical with the computed results that have been previously provided by Kömmerling using the POLYFLOW version. In addition, a detail investigation regarding the convergence of the cooling simulation software was carried out. In the second part of this research work, a critical overview of the mechanical model has been presented. The main scope of this section was to carry out a detailed investigation of all the aspects of the mechanical model. Throughout this research, aspects as the convergence behaviour of the software were thoroughly examined. The outcome of this detailed investigation was the development of a new version of the mechanical model. The present work has provided detailed insights and understanding of the performance of the mechanical software, and produced improved versions of the code. The work has identified a number of further developments that are required. Throughout the research period, strong and valuable synergies have been developed with previous and parallel research works between Swansea University and Kömmerling Kunststoffe, aiming to provide a better understanding of the parameters that affect the calibration process and the use of the simulation software.
