The ability to simulate aerodynamic flows using CFD methods has progressed rapidly over the last decades and has given rise to a change in design processes in aeronautics already. But more improvement is necessary to overcome the (still) existing lack in confidence in CFD usage, based on turbulence modelling. The TILDA project will offer methods and approaches combining advanced and efficient high-order numerical schemes (HOMs) with innovative approaches for LES and DNS in order to resolve all relevant flow features on tens of thousands of processors in order to get close to a full LES/DNS solution for 1billion degrees-of-freedom (DOF) not exceeding turn-around times of a few days. The TILDA project will provide both an improved physical knowledge and more accurate predictions of non-linear, unsteady flows near borders of the flight envelope - which will directly contribute to an enhanced reliability. The main highly innovative objectives, targeting at industrial needs read: Advance methods to accelerate HOM for unsteady turbulence simulations on unstructured grids. Advance methods to accelerate LES and future DNS methodology by multilevel, adaptive, fractal and similar approaches on unstructured grids. Use existent large scale HPC networks to enable industrial applications of LES/DNS close(r) to daily practice. Compact high-order methods offer a very high ratio between computational work per DOF combined to a low data dependency stencil, making these methods extremely well adapted for shared-memory parallel processors, and allow for efficient redistribution over an increased number of processors. Provide grid generation methods for HOM on unstructured grids with emphasis on valid curvilinear meshes for complex geometries, and accounting for mesh and solution quality. Provide suitable I/O and interactive co- and post-processing tools for large datasets. Demonstration of multi-disciplinary capabilities of HOM for LES in the area of aero-acoustics.

Hybrid-EVs and Full-EVs on the market are products where the Internal-Combustion-Engine (ICE) is supplemented by an electric-motor (HEV) or replaced by an all-electric power-train (FEV). Both approaches do not address lightweight or modularity inheriting the same disadvantages as conventional ICEV - Electrification of mobility must face a conceptual rEVOLUTION! This project breaks the paradigm of current Body-in-White (BiW) by delegating the whole structural function to a novel BiW archetype made up of a Multifunctional-Rolling-Chassis (MRC) enabled by a new generation of highly-hybridized structural components and complemented by a non-structural upper-body. This MRC will be the common basis for a family of user friendly vehicles differing by changing only the upper-body according to the customer demand. Advanced materials will enable the development of novel super-lightweight hybrid components complying with safety standards and recycling constraints, and enable the design of the innovative MRC for FEV leading to a further weight reduction of 40% over that achieved using the current state of the art in the SuperLIGHT-CAR project. The EVolution goal is to demonstrate the sustainable production of a 600 kg weight FEV by the end of 2015. To this end EVolution addresses the whole vehicle by prototyping, assembling, and disassembling, the most representative components (MRC, crash cross-beam, crash box, suspension sub-frame, side-door, A-pillar, and a multifunctional-hard-top) made from raw polymers and aluminum alloys commonly used in the automotive industry, to ensure compliance with EC Directive 2000/53/EC End-of life vehicle which imposes stringent requirements on the disposal and recycling of motor vehicles. Guaranteeing the safety and regulatory compliance, with a weight saving of 50%, each component chosen will prove, mutatis mutandis, the revolutionary potential of the EV solution in all components employed today in current high volume production.

The goal of this project is to reduce the power performance ratio within data-centres by improving the usability and usefulness of FPGAs, embedded CPU (eCPU), GPUs and multi/manycore accelerators in high-performance and low-power heterogeneous computing servers. We target applications between traditional super computing tasks (where huge amount of man-power can be spent for manual algorithm optimization) and general purpose data-centre applications (which have to run as they are w/o any optimization for hardware acceleration).\nThe consortium consists of partners from embedded systems and high-performance computing domains. We will combine our experiences in automatic software-to-hardware synthesis and hardware-software co-design from the embedded systems world with the hardware and application experience from the high-performance computing world.\nThe project focus will be on a) setting up a flexible server hardware system, offering a user-constrainted amount of CPUs, eCPUs, FPGAs, GPUs and multi/manycore processors; b) setting up a software development environment, easing up computing resources co-programming adapted fromexisting tools and runtime management techniques from the embedded system domain and leveraging state-of-the-art middle-ware communication and execution frameworks from the HPC domain; and c) demonstrate the effectiveness of both hardware and software environments from FiPS outputs with real world applications at four HPC application partners.

The ENOVAL project will provide the next step of engine technologies to achieve and surpass the ACARE 2020 goals on the way towards Flightpath 2050. ENOVAL completes the European 7th Framework Programme (FP7) roadmap of Level 2 aero engine projects. ENOVAL will focus on the low pressure system of ultra-high by-pass ratio propulsion systems (12 < BPR < 20) in conjunction with ultra high overall pressure ratio (50 < OPR < 70) to provide significant reductions in CO2 emissions in terms of fuel burn (-3% to -5%) and engine noise (-1.3 ENPdB). ENOVAL will focus on ducted geared and non-geared turbofan engines, which are amongst the best candidates for the next generation of short/medium range and long range commercial aircraft applications with an entry into service date of 2025 onward. The expected fan diameter increase of 20 to 35% (vs. year 2000 reference engine) is significant and can be accommodated within the limits of a conventional aircraft configuration. It is in line with the roadmap of the Strategic Research and Innovation Agenda for 2020 to have the technologies ready for Optimised conventional aircraft and engines using best fuel efficiency and noise control technologies, where UHBR propulsion systems are expressively named as a key technology. ENOVAL will be established in a consistent series of Level 2 projects in conjunction with LEMCOTEC for core engine technologies, E-BREAK for system technologies for enabling ultra high OPR engines, and OPENAIR for noise reduction technologies. Finally, ENOVAL will prepare the way towards maturing the technology and preparing industrialisation in coordination with past and existing aero-engine initiatives in Europe at FP7 and national levels.

The use of the extended finite element method in the scope of linear elastic fracture mechanics induces the integration of singular functions in terms of the stiffness matrix and in the computation of stress intensity factors using the interaction integral method. An adapted method is proposed in this paper to treat efficiently the three-dimensional case. The improvement is demonstrated by comparison with standard and other methods found in the literature. © 2012 John Wiley & Sons, Ltd. Source
