OpenFOAM: User Guide: snappyHexMesh

Web1 Introduction. In a nutshell, snappyHexMesh is a mesh generator that takes an already existing mesh (usually created with blockMesh) and chisels it into the mesh you want. But … snappyHexMeshis a fully parallel, split hex, mesh generator that guarantees a minimum mesh quality. Controlled using OpenFOAM dictionaries, it is particularly well suited to batch driven operation. Key features: 1. starts from any pure hex mesh (structured or unstructured) 2. reads geometry in triangulated … See more The overall meshing process is summarised by the figure below: This includes: 1. creation of the background mesh using the blockMeshutility (or any other hexahedral … See more Meshing controls are set in the snappyHexMeshDict located in the case systemdirectory. This has five main sections, described by the following: 1. geometry: specification of the input surfaces 2. … See more The command snappyHexMesh executes the meshing process. Adding the -helpoption, i.e. returns the list of available options By default, each of snappyHexMesh's phases, i.e castellation, snapping and layer … See more WebThe reason for this is that if snappyHexMesh is refining based on feature angles or local curvature, small ‘islands’ of higher refinement levels occur, and those seem to be locations where snappyHexMesh clearly has troubles getting a well-snapped mesh. Hence, I use equal values for minimum and maximum refinement per surface. individual assurance company phone number
