As a part of this training, there is included a CAD model of a complete water valve solid (see figure ).
The main objective of this tutorial is to prepare a given model of the water valve as an input model ready for meshing and running CFD simulation in an OpenFOAM.
A typical meshing software (in this tutorial OpenFOAM meshing tool snappyHexMesh) needs a surface model. A typical file format is .STL https://en.wikipedia.org/wiki/STL_(file_format)
A clean and waterproof surface model is to be created.
A general workflow (repeatable for any other case) is to be shown
