Cell Zone Generation
snappyHexMesh, meshing, cell zone generation, feature edges
Particular regions in a mesh could require unique properties such as the modeling of porosities or source terms. Therefore, cell zones have to be used in OpenFOAM®. Tobias shows in this tutorial how snappyHexMesh can be used to define such zones during the meshing stage directly. Based on the snappyHexMeshDict set-up, different quality levels regarding refinement and zone representation can be achieved. Especially the influence of the »featureEdge« feature is demonstrated in the training case. In the snappyHexMesh dictionary different cell zones are set to be created inside the mesh. The correct approximation of the shape design can be relevant in some investigations.

The available OpenFOAM® training cases are tested and built for different OpenFOAM® versions (not distributions) on a Linux machine. During the tests, only the OpenFOAM Foundation version of OpenFOAM® was used. Furthermore, the following software packages are required for most of the training cases: Salome®, ParaView®, and for optimization tasks, one also needs the open-source software DAKOTA®. The OpenFOAM® cases might work with the ESI version of OpenFOAM® but it is not supported. For the OpenFOAM® extend project, the training cases will probably not work as the code diverged too much. Additionally, there is no support for Windows-based and MAC-based OpenFOAM® versions.
