Descripción del proyecto
Geometría de alta fidelidad para simulaciones de ingeniería de la automoción y aeroespaciales
La superconvergencia y las simulaciones de flujo de alta fidelidad son un ámbito de investigación emergente fundamental para el diseño de aeronaves espaciales y vehículos de automoción. Por ejemplo, los modelos de simulación pueden ayudar a los ingenieros espaciales a desarrollar y probar nuevos algoritmos que optimicen trayectorias. El proyecto financiado con fondos europeos ESMORGA trabajará para lograr geometrías de alta fidelidad para simulaciones, y su implementación en paralelo para grandes corpus de datos. Se diseñó además un plan de evaluación de riesgos diseñado para garantizar que se pueda derivar al menos una teoría de superconvergencia subóptima. El Centro Nacional de Supercomputación de Barcelona se empleará en la implementación de esta herramienta de geometría de alta fidelidad, centro que cuenta con el superordenador MareNostrum 4, uno de los más potentes de Europa.
Objetivo
High-fidelity simulations using supercomputers play a key role in aerospace and automotive design for reducing the number of ground and in-flight tests. The mesh lies at the heart of the simulation: it reproduces the geometry using elements that, for engineering applications, are required to be curved (high-order). This project exploits geometric superconvergence: extra accuracy using lower order elements. The main goal is to transform observed geometric superconvergence into theory. The originality of this work is to derive the mathematics behind geometric superconvergence including theoretical limits and to develop a parallel code for High Performance Computing (HPC). The action features a two-way transfer of theoretical and practical knowledge between the fellow and the host institution in the topics of superconvergence, high-fidelity geometry simulations and HPC. The fellow will be integrated in the internationally recognized Geometry and Meshing for Simulation group at the Barcelona Supercomputing Center (BSC). This action is devised to have significant impact on the fellow’s career, becoming an expert in superconvergence both for numerical approximations and geometry within the unstructured high-order simulations community focused on aircraft design. The proposal has the potential to establish the fellow as core scientist in the emerging research area of superconvergence and high-fidelity flow simulations, allowing the candidate to start and lead a new research group. The work packages and methodology have been devised to reach the goals on high-fidelity geometry for simulation including parallel implementation for large data clustering. A risk assessment plan has been designed ensuring that at least suboptimal superconvergence theory can be derived. The BSC infrastructure will be essential for the implementation of this high-fidelity geometry tool; it houses MareNostrum4, one of the most powerful supercomputers in Europe.
