Figure: Preview of the Francis water turbine geometry.

The input for this methodology consists of surface geometry in (.STL) file format10.1. Original files can be found in directory tutorials/francis-full-snappy/meshFactory/mesh-rotor/constant/triSurface. STL model can be viewed in paraview by opening following files:

  • blade-rot.stl
  • drafttube.stl
  • guide-blade.stl
  • guide-hub.stl
  • guide-shroud.stl
