Abstract
Policy makers and regulatory bodies are demanding the aerospace industry reduces CO2 emission by 50% and NOx emission by 80% by 2020. In order to meet these drastic demands and ensure affordable air travel in the future, it is essential to make lighter aircraft which will use minimum fuel. The aerospace research community recognises the need to make a dramatic performance improvement and is considering several new aircraft concepts that move away from the conventional two-wing-one-fuselage configuration. This brings new challenges to aircraft design. A wing is a highly complex structure to design as it needs to consider the complex interaction between aerodynamics and structural behaviour. The current design practice is therefore very much based on using the previous successful design data. The challenge of departing from the conventional aircraft is that there are limited successful historical design data that is applicable to new concept aircraft. Once we have a wing design, however, there are sophisticated computational methods that analyse how the wing behaves under external flight conditions.
In fact, there has been a significant level of development in computational analysis methods taking advantage of growing computational power. A prime example of this is the recent development in the computational modelling of materials. Using this technology, new advanced materials can be created in half the time that traditional material development takes and the return on investment in computational materials research has been estimated at between 300 - 900%.
This fellowship is at the heart of developing sophisticated computational methods to design aircraft configurations that have not been considered before. The majority of the current methods analyse how a given material or structure responds to the external environment such as in flight at speed Mach 0.8, 38000 ft. What is different about the methods in this research is that they are inverse of the analysis methods: They will determine the best combination of advanced material and structural configuration based on the external environment and hence design the optimum wing for the given flight conditions.
My research approach is to represent the design problem as a set of mathematical functions and develop computational methods to find the optimum solution. The methods will therefore, find the optimum design for both materials and structural configuration at the same time. The outcome of this fellowship will provide engineers with a sophisticated tool to design complex aircraft structures. The tools will be developed and disseminated in a way that they can be used on a range of other complex engineering problems.
The UK has 17% of the global aerospace market share with revenue of £24 billion and is responsible for 3.6% national employment. With the international civil aerospace market forecast to grow to $4 trillion by 2030, the UK market has the opportunity to grow to $352 billion by 2030. It is critical that the UK develops this unique capability to ensure we maintain the market share of these high value products and processes and its economy has the opportunity for growth. Furthermore, the weight savings which will be made from optimum use of materials lead to meeting the emission targets, thus ensuring sustainable environment for the future generations.

Planned Impact
(1) Industry and Economy
This research has a significant societal and economic impact for growth. The material industry in the UK has an annual turnover of around £197 billion and export values at £50 billion. Tailoring advanced materials for specific applications will lead to more high value products and processes which have strong potential to bring sustainable growth and high economic value to the UK. A variety of case studies have shown that the use of computational modelling and optimisation in materials and structural design reduced lead time to product by 50-80%. Taking this a step further to develop computational methods of simultaneously optimising both materials and structures will strengthen the UK as a global leader and enhance the national economy. Material innovation has been identified as particularly critical to the aerospace sector. The aerospace industry employs over 84100 (3.6% of national employment) with the revenue of £24 billion, 17% of the global market share, second only to the USA. The international civil aerospace industry is forecast to grow and to be worth approximately $4 trillion by 2030 and the UK has the opportunity to grow its market to $352 billion by 2030. The aerospace industry in the UK therefore, is said to have a "tremendous opportunities for growth" and is considered to be of strategic importance for the future of the UK economy. The unique capability to design revolutionary aircraft concepts will grow the national economy by creating jobs and ensuring a globally leading market position for the UK. In addition, the use of engineering optimisation to produce the lightest and the most efficient aircraft provides a route to minimise the overall fuel burn and contribute to the sustainable future.
(2) People and Society
Maintaining global leadership in high value products and process through materials and aerospace structures will attract manufacturing industry and increase the global market share, thus growing the UK economy. This will create more jobs and wealth which will ultimately benefit people and the society. In addition, the advanced materials and optimisation methods developed within this research will lead to the lightest aircraft and to low operating and through-life costs. With the increasing risks and uncertainties of fuel prices, this effort is critical in ensuring that future air travel remains affordable. The research also addresses the sustainability of air travel via low emissions through low fuel burn and optimising existing aircraft for re-use. This work will therefore benefit the environment and the future generations.
(3) Investigator and researchers
The potential of high impact scientific research in this fellowship provides an opportunity for myself and my researchers to become world leaders at the interface of materials and structures. This research integrates materials and structures which have traditionally been considered two distinct disciplines. Therefore the integrated expertise of materials and structures from a design perspective is rare and this unique expertise will firmly place me at the forefront of the state of the art and make my researchers distinctive and highly employable. The fellowship will lead to the identification of new research challenges and open up new opportunities to secure future funding from industry and funding bodies. Working closely with industrial partners provides a route for the researchers to make a direct impact in engineering industry and society.

| Description | (1) New architected materials with spatial variations and continuous interfaces can be discovered using the new method developed in this project. (2) When applied to optimize for a load carrying functionality by minimizing strain energy, the optimum material configuration is solid isotropic material. This means porous material and microstructures lattices will give a heavier structure than a solid material. This needs to be further investigated for the material stress and buckling requirements however, this also intuitively makes sense in many design cases. (3) The porous materials are more likely to be optimum for multifunctional (and probably multiphysics) applications and this is currently under investigation. (4) New software architecture and infrastructure incorporated which increased the efficiency of the topology optimization method by an order of magnitude. The resulting method is at least an order or magnitude faster than the state of the art level set topology optimization method internationally. (5) Multiphysics multiscale topology optimization method established, applied to a wide range of problems including mechanics, dynamics, eigenvalues, fluid, heat transfer and acoustics. (6) topology optimization used to investigate and discover new material designs for nonlinear and metamaterials. (6) level set topology optimization method with automatic differentiation established, thus extending the application areas to any PDE-based governing equations including non-finite element methods. (7) the new topology optimization methodology can be integrated with the standard CAE and MDO framework (and demonstrated by implementing in OpenMDAO, NASA's opensource multidisciplinary design optimization software). |
| Exploitation Route | The results potentially influence the future research direction of the porous material and lattice material research community as many understand the porous/lattice material will offer a lighter structural solution. Our research reveals that when a structural load carrying functionality is considered, this is unlikely to offer a lighter solution, but they have substantial potential when multi physics and multifunctionalities are considered. It can be applied to study non-intuitive and complex design space such as nonlinear metamaterials. The topology optimization method can also been used to tailor and 3D-print customized designs for vascular networks and other bio-implants. The entry barrier to topology optimization has been significantly lowed so engineering industry can easily access designs offered by topology optimization. |

| Description | One major impact area is in steering the future research direction in aerospace, defence, transportation and energy sectors. The outcome of the project demonstrated the potential benefits of multiscale multidisciplinary optimization, which led to invitations to give keynote and plenary lectures at conferences in materials, mathematical geometries and computational mechanics. These further led to invitations to advise on future NASA research in computational materials, three-year follow-up funding to realize the multiscale optimization method by DARPA and advisory documents for aerospace and energy agencies and industries, all of which feature optimization as a core technology for enabling future materials and systems optimization. With my research expertise, I was able to lead and found steering committees that bring together the industrial and academic leaders and collaborate on advancing digital engineering and transformation through AIAA and invite-only workshops by the US departments of energy and defence, and national academy of engineering. While my efforts to disseminate my research and community activities have been in the international venues, the invitations and recognitions to make these impacts have been predominantly in the US government and industries, and as a result, this project's impacts have been more influential and immediate in the US and consequently propagating back to Europe and Asia. Personally I find this somewhat disappointing that my research did not lead to more opportunities in the UK but it is pleasing to see the impacts returning to the UK via the US agencies. These prominent roles have led me to discussions on the importance of the top-down system level approach across material scales and I am now actively funded and collaborating directly with a number of industries around the world in the areas of aerospace, automotive and new forms of transportations and battery, via which I am making the immediate impacts. Another impact area is the research culture at least in the computational mechanics and computational mathematics. This project enabled me to publish highly impactful papers (Google scholar citation in 2015 was 284, the citation up to Mar 15, 2022 is 248). I believe this was a major contribution towards being elected to be the secretary general of International Society for Structural and Multidisciplinary Optimization (ISSMO), the executive committee member of the US Association for Computational Mechanics (USACM) and the deputy chair for the AIAA Multidisciplinary Design Optimization Technical Committee. I founded and initiated the women researchers chapters for all these professional communities, which actively meet and organize various supporting and mentoring activities. During my tenure, the computational mechanics communities made the first award to a women researcher and also saw the first women speakers for the plenary, semi-plenary and keynote lectures at these meetings. I have several women researchers that regard me as mentors around the world and I am regularly invited to interview and advise a number organizations and universities in increasing women participations. I believe the fellowship was instrumental in enabling me to initiate these cultural changes in our male-dominant research and academic communities. Another important area of impact is the people and training. All my researchers who were funded by the fellowship moved on to continue their research in this area, either as a university academic or industrial research. The fellowship research activities were leveraged to enable several other related projects and the current activities, most of whom are continuing their research and initiated relevant research branches in the UK, Europe, China, Brazil and the US. Some of these people are already becoming leaders establishing their own research groups and expertise. I have had discussions over the last few years all the major finite element and topology optimization software companies including a UK start-up who is basing their software on my method and the opensource code and growing successfully across Europe. I have initiated the discussion to promote the opensource code culture and standard in topology optimization in collaboration with multidisciplinary design optimization communities and started activities (e.g. committees, workshops, seminars, meetings) in the USSMO and AIAA MDO TC communities, with the aim to enable and establish more collaborative and reusable/reproducible research software and optimization-led digital engineering practice. This is an area I am expecting to realize more impacts by bringing the research and engineering closer and lowering the entry barrier to application of the latest technology via software. |

| Organisation | Voxel Tech Inc. |
| Country | United States |
| Sector | Private |
| PI Contribution | Using the level set method in topology optimization has several advantages, such as being able to handle complex topological changes and having a crisp definition of the boundary. However, a common criticism is that they tend to be slower in convergence than the traditional density-based approach (such as SIMP [1]). One reason for this slowness is attributed to having to search through grid points, such as when updating the level set functions and finding the nearest neighbor of a grid point. For example, a popular method for updating the level set function, the Fast Marching Method, has an algorithmic complexity of O(NlogN) because it uses a min heap data structure for accessing grid values. This becomes very costly and slow as the number of grid points (N) increases. The efficiency of the level set method can be substantially improved by using a hierarchical data structure (VDB [2]) designed to take advantage of the level set method's unique characteristics. The hierarchical data structure is a volumetric dynamic grid that is similar to B+ trees and allows for the efficient storage and manipulation of sparse volumetric data. By arranging blocks of the grid into a hierarchical structure that resembles a B+ tree, it can be shown that the structure can support fast random, sequential, and stencil access (average O(1)) to the grid data. This fast access speeds up the level set update and associated computations such as calculating the normal at the boundary. |

| Title | OpenLSTO V0.1 - open source level set topology optimisation |
| Description | OpenLSTO is an open-source software for level set based structural topology optimization, written in C++. The topology optimization method deals with the problem of determining the optimal layout of material and connectivity inside a design domain in order to obtain the best structural performance. Level Set Method was originally developed as a mathematical tool for tracking the motion of interfaces. Its natural handling of topological changes coupled with a clear and smooth interface representation led to its use for structural topology optimization. This first light version implements the M2DO lab's level set topology optimization method to solve the problem of minimizing compliance (maximizing stiffness) under a volume constraint in a 2D design domain. It has been designed with ease of installation and use in mind. This means that, wherever possible, a conscious effort was made to develop in-house code components rather than relying on third-party packages or libraries. In simple cases (serial version with no external libraries), the code can be compiled and executed with just a C++ compiler. Extended capabilities using externally provided software are to be included in the next, more advanced version. |
