Welcome to Day 6. By now you should have a good understanding of the very basics of OpenFOAM. Today we will further improve your knowledge by going in the direction of real-world applications. You cannot mesh everything with the simple blockMesh utility. For real life geometries you will need more. Today you will learn this by creating your own
- geometry
- mesh
Go back to "3 weeks" series.
Contents
Open source geometry creation
Here you will get a detailed introduction into two alternatives for the creation of geometries as inputs for a CFD project in OpenFOAM
- Salome
- Onshape
Meshing in OpenFOAM
The saying goes "Who owns the mesh, owns the solution". In OpenFOAM there are several ways to set up a mesh. On the one hand you can import it from external tools, you can use the simple blockMesh utility [1] [2] [3] or you can create your arbitrary mesh with snappyHexMesh. This tutorial will show you all the possibilities. The topics covered are:
- mesh quality assessment
- mesh conversion from external tools
- blockMesh
- snappyHexMesh
Meshing with cfMesh
An alternatives for snappyHexMesh is cfMesh. In this tutorial you will get a compact introduction into the work flow of the basics. The following topics are covered:
- geometry definition
- basic mesh refinement
- local refinement along STL files
- layer addition
How To Build a complete OpenFOAM Project - Exhaust manifold
In this tutorial you will learn how you can start your own simulation project. There is a heavy focus on meshing in Videos 1-10. You will learn about:
- starting a project
- preparing the geometry
- repairing the geometry
- surface triangulation
- STL preparation
- first meshing
- mesh optimization
End of Day 6
Today you made a big step towards the real life application of CFD in OpenFOAM by learning and understanding how to create a mesh in OpenFOAM. Tomorrow we will continue with simulations including turbulence modeling. If you've finished the day with time to spare, why not try the additional examples below!
See you tomorrow!
Additional examples
snappyHexMesh – Single region
Mesh a flange geometry and simulate heat transfer in it using scalarTransportFoam.
- The aim of the tutorial is to give a basic introduction to single region meshing with the meshing tool snappyHexMesh
- Understanding the advantages of snappyHexMesh
- Understanding the three basic steps of snappyHexMesh
snappyHexMesh – Multi region
In this tutorial a geometry with more than one region is meshed using snappyHexMesh and simulated using chtMultiRegionFoam.
- Understanding multi region meshing with the meshing tool snappyHexMesh
- Multi region simulations
