Thin Gap Meshing
snappyHexMesh, simpleFoam, mesh generation for internal flow, gap refinement
Different engineering designs contain small gaps, which are sometimes challenging to handle for the meshing procedure. SnappyHexMesh allows one to use different techniques to provide suitable refinements. One of these methods is described in this tutorial. For the refinement strategy, a separate triangulated surface file is used for the »regionRefinement« procedure. However, snappyHexMesh also allows the usage of a gap refinement keyword, which is not presented here. After the meshing, a steady-state solution is calculated. A total calculation time of around 10 minutes is required for ordinary computers.
There are many ways to reach the final mesh

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.
