PhD Thesis by John Ewer.methodology that was developed for the re-use of the legacy CFD software in order to providea framework for the research required for this project. The reverse engineering and reengineeringprinciples developed during this investigation are of significant interest in their ownright, particularly when one considers the large amount of useful legacy code that is still in usebut is often difficult to maintain or to integrate with newer applications.Chapter 4. This chapter describes the creation of the prototype CFD system from the reengineeredlegacy software. This is the "vehicle" that was to be used for the investigations intothe potential benefits of interactive control.Chapter 5. This chapter discusses the validation of the prototype CFD environment andcompares the run-time behaviour with the legacy software from which it evolved. This wasnecessary to check that the reverse-engineering process has not corrupted the functionalbehaviour of the software.Chapter 6. This chapter introduces a set of simulation cases with their results, and consequentinterpretations. These test cases were used to investigate the potential benefits of interactivecontrol and monitoring.Chapter 7. This chapter discusses some preliminary findings of research that was conducted intosolution optimisation. The two techniques that were investigated were automated dynamicsolution control and a new solver technique called a group solver.Chapter 8. This chapter offers conclusions about the benefits of these investigations.Chapter 9. This chapter indicates the need for additional research. This additional research couldnot be completed or fully investigated due to time constraints.The Appendices include technical descriptions of the algorithms, design and developmenttechniques employed in the particular class of CFD code used during this research. Publishedpapers, from the author, which are directly relevant to this investigation have also been includedin their entirety, so that referring sections of this thesis could be written more concisely.1-13
