Inputs

• meshQuality [Default]

  Use 0-2 to auto generate the parameters for meshQualityControls

• castellatedMesh [Default]

  Set to True to castellated mesh (default: True).

• snap [Default]

  Set to True to snap mesh to the surfaces (default: True).

• addLayers [Default]

  Set to True to push mesh away from surfaces and add layers (default: False).

• nCellsBetweenLevels [Default]

  Script variable snappyHexMeshDict

• maxGlobalCells [Default]

  An intger for the maximum number of global cells (default: 2000000).

• surfaceFeatureLevel [Default]

  An integer for the extract features refinement. Default is None which

  means implicit meshing feature will be used.

• expansionRatio [Default]

  Layers expansion ration (default: 1.1)

• finalLayerThickness [Default]

  Thickness of final layer (default: 0.7)

• minThickness [Default]

  Minimum thickness for layers (default: 0.1).

• nLayerIter [Default]

  Overall max number of layer addition iterations. The mesher

  will exit if it reaches this number of iterations; possibly with an

  illegal mesh (default: 50).

• additionalParameters [Optional]

  Additional parameters as a valid c++ dictionary. Additional values

  will overwrite the values from the other inputs above.

Outputs

• snappyHexMeshDict
