“…Some recent publications in the MDO literature have reached similar conclusions to ourselves about the desirability of workflow approaches (e.g. Shi et al 2005;Bereneds et al 2008;Moore et al 2008), but we observe that the published descriptions appear to use bespoke software rather than workflow tools.…”

Multi-disciplinary design optimization (MDO) is the process whereby the often conflicting requirements of the different disciplines to the engineering design process attempts to converge upon a description that represents an acceptable compromise in the design space. We present a simple demonstrator of a flexible workflow framework for engineering design optimization using an e-Science tool. This paper provides a concise introduction to MDO, complemented by a summary of the related tools and techniques developed under the umbrella of the UK e-Science programme that we have explored in support of the engineering process. The main contributions of this paper are: (i) a description of the optimization workflow that has been developed in the TAVERNA workbench, (ii) a demonstrator of a structural optimization process with a range of tool options using common benchmark problems, (iii) some reflections on the experience of software engineering meeting mechanical engineering, and (iv) an indicative discussion on the feasibility of a 'plug-and-play' engineering environment for analysis and design.

“…Initiatives from NASA [Moore et al 2008], Boeing [OSEE 2009] and Airbus [Farail et al 2006] show that the aerospace industry not only embraced the idea of open source but also adopts established solutions from the software industry like Eclipse [Eclipse 2009] for their domain specific needs.…”

The current challenges of the aviation industry call for the development of new and revolutionary aircraft concepts. In general, the task of developing new aircraft is risky and an extremely complex task, and aircraft manufacturers seek to control this complexity by adopting an evolutionary approach. Introducing new ways of controlling this complexity has the potential benefit of reducing the risk associated with aircraft development and enabling the development of revolutionary aircraft. One such new way is based on the application of agile principles.This paper discusses the application of agile principles on aircraft development processes to eliminate to a certain degree the involved complexity of conventional aircraft development processes.

“…Permissive open source licenses, also called non-viral licenses, provide a good balance between protecting the integrity of the core framework and allowing for integration with commercial and proprietary plugins. 1 Under NOSA, OpenMDAO can be freely distributed and used. If changes are made to any of the modules delivered as part of OpenMDAO, the resulting new modules retain the NOSA license.…”

This paper describes the progress made in the development of OpenMDAO, an open source framework for performing Multidisciplinary Analysis and Optimization (MDAO). NASA intends to use OpenMDAO to aid in the design of unconventional aircraft, but the general structure and methods may be applied to solve any number of engineering-related design problems. The framework currently supports data passing capabilities, and several example problems have been executed with it. Recent work has focused on enabling the creation of more complex MDAO strategies, such as collaborative optimization and surrogate modeling techniques. An example is presented that demonstrates an implementation of the surrogate model generation using Kriging surrogate models augmented with the expected improvement method.
