Accelerating the FlowSimulator: improvements in FSI simulations for the HPC exploitation at industrial level

Abstract

High-performance computing systems enable the use of computationally intensive models in aircraft design simulations, but challenges arise with communication times and memory consumption as the number of cores scales up.This paper presents improvements to the mesh partitioner and mesh deformation methods for highly parallelized simulations within the FlowSimulator framework. The results are obtained for a simple wing test case, a full-aircraft configuration and an aircraft research model. Improvements to the mesh partitioner are presented that allow for even larger and more parallelized simulations than was previously possible in the framework. In addition, scaling results from a mesh deformation method based on the elastic analogy are presented, which shows superior scalability compared to the conventional radial basis function method. This improves the overall suitability of the toolchain for large parallelization and highlights its potential for industrial applications. The results demonstrate a step forward towards an optimal exploitation of high performance computing systems for solving coupled simulations in the aerospace industry.
