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 compressor stator region.

 cd $WM_PROJECT_USER_DIR/run
 mkdir -p turbomachinery-CFD/meshFactory/c1/stator
 cd turbomachinery-CFD/meshFactory/c1/stator
 cp -r $WM_PROJECT_INST_DIR/Turbomachinery-CFD-XX.XX/
/tutorials/meshFactory/c1/stator/*     ./
The input .STL files are located in constant/triSurface and can be directly viewed in paraview.

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

Interface between rotor and stator part is user defined cylinder. It can be simply created in paraview.^13.4

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