Thin Gap Meshing and Refinement
Using additional STL files for region refinement
SnappyHexMesh allows using different strategies to refine different surfaces and regions. However, discretizing thin gaps in the domain can result in a challenging topic. Especial critical are meshing procedures in which only triangulated surface are available. As already mentioned, OpenFOAM allows different techniques to refine thin gaps. One of them is described in this tutorial.
