A Crash Introduction to Near-wall Treatment in RANS Turbulence ModellingIn the near-wall region, the flow property changes dramatically. The flow region can be divided into three layers,the viscous...

It is often the case that the mesh quality in thin gaps is difficult to control when using snappyHexMesh. Some times there would be no ample mesh layers to fully represent the flow properties in th...

To well capture the properties of fluid near boundaries, the high quality layered mesh should be taken care of.Enable LayeringTo enable the layering functionality, set the addLayers option to true ...

Manually-assigned feature edges can give users more control over where they want to refine, without bothering with the two angles, i.e. includeAngle & resolveFeatureAngle, and worrying about whethe...

In the meshing process, if the geometry has sharp angles that you want to resolve, then edge refinement is needed, otherwise, the meshed edge would look blunt, which is not acceptable.One should pl...
