Files Preparation - Spiral Region

For creating new mesh with snappyHexMesh it is recommended to create new OpenFOAM test case just with system and constant.

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

# paraview

Seven .STL files are presented, namely: guide-blade.stlguide-hub.stlguide-shroud.stlinflow.stlinterface-guide-rot.stlspiral-dip.stlspiral.stl.

Interface between rotor and spiral part (interface-guide-rot.stl) is the same as for rotor region (see Section [*], page [*]).

The initial idea is to create following mesh boundaries: inlet, spiral-walls, interface. Their number and names may change during the creation process.
