PhD Thesis by John Ewer.membership groups offered any benefits to CFD simulation and to ascertain if interactive controlof groups was in any way beneficial.Also researched was the potential for automated solution control using the knowledge gainedduring the optimisation research mentioned above.1.4 Contribution to knowledgeThe following summary indicates the significance of this work based on the limitations andproblems of existing CFD systems in general and the legacy source CFD code in particular.1.4.1 Development of an incremental re-engineering methodologyThe techniques created to reverse-engineer and re-engineer the legacy FORTRAN CFD code,using a novel incremental approach that preserves functional consistency, are likely to provebeneficial to a wide range of legacy numerical software systems both within and outside of thedomain of CFD research.1.4.2 Investigation of new CFD techniquesThe prototype system has been used to research numerous enhancements made possible by thestructure, availability of dynamic memory allocation and the Object Oriented design paradigmimposed during the software re-engineering. This has allowed research into the benefits ofunstructured group solvers [EWER99-3] to be investigated as well as research into theautomation of interactive control experiences using Knowledge Based System (KBS) controltechniques.Other techniques, outside of the scope of this thesis, are also being developed within theSmartfire framework [TAYLOR96]. This work is facilitated by the open and extensible softwarearchitecture. These techniques include run-time mesh adaption, fire modelling using solidcombustion, modelling of thermal radiation and simulation of flash-over.1-9
