Architecture and Construction Principles for Computational Fluid Dynamics Software for Engineering in Industry;Thesis

摘要

For flow simulation around (parts of) aerospace vehicles, aerospace industry needs CFD software. The structure of software is created in the architectures of the various aspect-systems and in the construction of the software. The central question of the thesis is 'How to achieve a structure of CFD software for engineering in industry suited for support of timeliness, testability, and adaptability'. The central question is answered in the form of architecture and construction principles, which are basic forms, rules, or recommendations with respect to architecture and construction. Major principles are to maintain the structure of the mathematics in the structure of the CFD software, to design for expected changes, and to incorporate exception handling and other standard sound software approaches. The set of architecture and construction principles has been developed and applied during a project for the iterative development of a specific CFD flow solver, SOLEQS. The flow solver is included as a demonstrator of application of the architecture and construction principles. The relevance of the current work is that application of the principles can support research organizations to deliver innovative CFD software that fulfills industry's requirements for engineering tools. Such software then acts as carrier for knowledge transfer from research organizations to industry.
