This post explains briefly how can we get a smooth mesh when using the snappyHexMesh in OpenFOAM 2.0.<\/p>\n

The main ingredient is the ‘surfaceFeatureExtract’ utility.<\/p>\n

Here are the steps:<\/p>\n

1- blockMesh: the BCs can be defined here, example: inlet and outlet patches.<\/p>\n

2- extract the surface edge from the .stl file, example: tank.stl
\ncommand : “surfaceFeatureExtract -includedAngle 150 -writeObj constant\/triSurface\/tank.stl features”<\/p>\n

this utiliy will create .eMesh file in \/constant\/triSurface\/ : example tank.eMesh<\/p>\n

3- in the snappyHexMeshDict, edge refinement is made by referring the eMesh file name, example: tank.eMesh.<\/p>\n

4- run the snappyHexmesh utility.<\/p>\n

Enjoy!<\/p>\n","protected":false},"excerpt":{"rendered":"
