Description	This Dataset contains the test case definition and reference data for the Taylor-Green Vortex (TGV) test case which builds the validation test case in the GALÆXI Paper (Section 5). Incompressible TGV (Ma=0.1) according to (Link): J. DeBonis, Solutions of the Taylor–Green vortex problem using high- resolution explicit finite difference methods, in: 51st AIAA Aerospace Sciences Meeting, 2013, p. 382 Compressible TGV (Ma=1.25) according to: J.-B. Chapelier, D. J. Lusher, W. Van Noordt, C. Wenzel, T. Gibis, P. Mossier, A. D. Beck, G. Lodato, C. Brehm, M. Ruggeri, C. Scalo, N. Sandham, Comparison of high-order numerical methodologies for the simulation of the supersonic taylor-green vortex flow, submitted to Physics of Fluids (2024). Executable of FLEXI/GALÆXI can be built using the `build.py` script: `python3 build.py ./build-folder ./userblock.txt` Note: Please ensure that all necessary dependencies of GALÆXI/FLEXI are available (including CUDA) and a Python3 environment is installed on the system.
