Mixed Fidelity Aerodynamics and Aero-Structural Optimization for Wings

In this paper we present mixed fidelity aerodynamic and aero-structural optimization methods for designing wings. A novel shape design methodology has been developed - it is based on a mix of the automatic aerodynamic optimization for a reference aircraft model, and the aero-structural optimization for an uninhabited air vehicle (UAV) with a high aspect ratio wing. This paper is a significant step towards making it possible to perform all the core processes for aerodynamic and aero-structural optimization that require special skills in a fully automatic manner - this covers all the processes from creating the mesh for the wing simulation to executing the high-fidelity computational fluid dynamics (CFD) analysis code. Our results confirm that the simulation tools can make it possible for a far broader range of engineering researc...

The goal of this SHAPE project, a collaboration with the PDC Center for High Performance Computing at the KTH Royal Institute of Technology (KTH-PDC), was to develop automated procedures for carrying out CFD analysis in the field of aerodynamic optimization and design. The project is a significant step towards automation of the core processes that ordinarily would require specialist skills, such as creation of the simulation mesh, thus assisting a broader sphere of engineers to design aircraft in more efficient and simpler ways.

The main objective of the conducted work was to realize cross-infrastructure services that enable the desired perceived seamless access to a combined infrastructure offering by both EGI and EUDAT services in pairing their data and high-throughput computing resources together. This document concentrates on the phase after the definition of the generic use case and depicts in detail the challenges encountered by the early adopters, the resulting new requirements and the identified solutions.

Automation of High-Fidelity CFD Analysis for Aircraft Design and Optimization Aided by HPC

2020 28th Euromicro International Conference on Parallel, Distributed and Network-Based Processing (PDP), 2020

The aircraft model/geometry is defined by a Common Parametric Aircraft Configuration Schema (CPACS) file, and the analyses are facilitated using high performance computers (HPC). As the computational capability of the available HPC systems is a limiting factor in the complexity of analyses that can be performed, a detailed performance analysis of the open source CFD code SU2 is undertaken and the profiling and performance analyses for large simulations are carried out.

The guide covers a wide range of topics from the description of the hardware of the Intel® Xeon Phi™ coprocessor through information about the basic programming models as well as information about porting programs up to tools and strategies how to analyse and improve the performance of applications. The guide was created based on the PRACE-3IP Intel® Xeon Phi™ Best Practice Guide. New is the inclusion of information about European Intel® Xeon Phi™ based systems. The following systems are now described: •Avitohol @ IICT-BAS, Bulgary, MareNostrum @ BSC, Spain, Salomon @ IT4Innovations, Czech Republic, SuperMIC @ LRZ, Germany. Furthermore, the following new sections are included: OpenMP 4.x Offloading, OpenCL, Intel Cilk Plus / MYO, Information about some selected applications ported to Intel® Xeon Phi™, Benchmark results using e.g. the PRACE Accelerator Benchmark Suite. Several existing sections have been updated to reflect recent changes.

Round planetary nebulae are the minority of objects. In case of those objects that underwent a very late helium flash (called VLTP or &quot;born-again&quot; PNe) it seems to be different. The first, hydrogen rich PN, is more or less round. The ejecta from the VLTP event is extremely asymmetrically. Angular momentum is mostly assumed to be the main reason for the asymmetry in PNe. Thus we have to find processes either changing their behavior within a few hundred to a few thousands of years or change their properties dramatically due to the variation of the abundance. They most likely have a strong link or dependency with the abundance of the ejecta.
