Assessment of the fluid-structure interaction capabilities for aeronautical applications of the open-source solver SU2.
Proceedings of the VII European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2016)(2016)
Abstract
We report on an international effort to develop an open-source computational environment for high-fidelity fluid-structure interaction analysis.In particular, we will focus on verification of the implementation for application in computational aeroelasticity.The capabilities of the SU2 code for aeroelastic analysis have been further enhanced both by developing natively embedded tools for the study of largely deformable solids, and by wrapping it using Python tools for an improved communication with external solvers.Both capabilities will be demonstrated on relevant test cases, including rigid-airfoil solutions with indicial functions, the Isogai Wing Section, test cases from the AIAA 2nd Aeroelastic Prediction Workshop, and the vortex-induced vibrations of a flexible cantilever in the wake of a square cylinder.Results show very good performance both in terms of accuracy and computational efficiency.The modularity and versatility of the baseline suite allows for a flexible framework for multidisciplinary computational analysis.The software libraries have been freely shared with the community to encourage further engagement in the improvement, validation and further development of this open-source project.
