Figure: Preview of the Kaplan water turbine geometry. Three regions here: spiral; rotor; drafttube;

The input for this methodology consists of surface geometry in (.STL) file format11.1. Original files can be found in directory tutorials/kaplan-full-snappy/meshFactory/mesh-rotor/constant/triSurface. STL model can be viewed in paraview by opening following files:

  • align-rot-draft.stl
  • align-rot-guide.stl
  • blade-guide.stl
  • blade-rot.stl
  • hub-guide.stl
