This Dataset contains the setup data for the NASA Rotor 37 test case which corresponds to the application section in the GALÆXI Paper (Section 6).

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. Moreover, the NASA rotor test case is a large scale setup, such that a consumer GPU/CPU might not be able to run the case.
