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.

1 3 mkdir -p turbomachinery-CFD/meshFactory/c1/rotor
1 3 cd turbomachinery-CFD/meshFactory/c1/rotor
1 3 cp -r $WM_PROJECT_INST_DIR/Turbomachinery-CFD-XX.XX/
/tutorials/meshFactory/c1/rotor/*     ./

The input .STL files are located in constant/triSurface and can be directly viewed in paraview.

Notice the model dimensions are in millimeters, not yet converted to meters. Three .STL files are presented, namely c-housing.stlc-wheel.stl and c-interface.stl.

Interface between rotor and stator part is user defined cylinder. It can be simply created in paraview13.2.

The initial idea is to create following mesh boundaries: inlet, inlet_wall, interface and wheel. Their number and names can change during the creation process.
