Files Preparation - Rotor Region
For creating new mesh with snappyHexMesh it is recommended to create new OpenFOAM test case just with system and constant directory and with empty directory 0. Go to your user directory and create directories for turbine rotor.
mkdir -p turbomachinery-CFD/meshFactory/t1/rotor
cp -r $WM_PROJECT_INST_DIR/Turbomachinery-CFD-XX.XX/
Interface between rotor and stator part is user defined cylinder. It can be simply created in paraview12.2.
The initial idea is to create following mesh boundaries: outlet, interface, outlet_wall and wheel. Their number and names can change during the creation process.
