Kaplan Turbine - Mesh Generation Using snappyHexMesh
Computational meshes are generated for each region individually. In this tutorial all the meshes are created using snappyHexMesh OpenFOAM application. The input for snappyHexMesh is surface model in set of .STL files. It is recommended to create temporal directories just for creating the mesh, later the mesh is copied to the case directory.
For effective work all the mesh creation process is done by script. Following section shows the manual way step by step.
