Keywords​

castellatedMesh [boolean]​

Flag to run/skip castellation stage

castellatedMesh yes; // no

snap [boolean]​

Flag to run/skip snapping stage

snap        yes; // no

addLayers [boolean]​

Flag to run/skip layer addition stage

addLayers   yes; // no

singleRegionName [boolean] OPTIONAL​

Single region surfaces get patch names according to the surface only. Multi-region surfaces get patch name surface "_ "region. Default is true

singleRegionName  yes; // no

mergePatchFaces [boolean] OPTIONAL​

Avoid patch-face merging. Allows mesh to be used for refinement/unrefinement. Default is true

mergePatchFaces yes; // no

keepPatches [boolean] OPTIONAL​

Preserve all generated patches. Default is to remove zero-sized patches (false).

keepPatches     no; // yes

mergeTolerance [scalar]​

Merge tolerance. Is fraction of overall bounding box of initial mesh. Note: the write tolerance needs to be higher than this.

Debugging​

debug (label) OPTIONAL​

Debug levels to write intermediate mesh data. Use debugFlags instead for better control

Example

debug     1;

debugFlags (List) OPTIONAL​

Provides fine-grain control over the debug output, including:

  • mesh: write intermediate meshes
  • intersections: write current mesh intersections as .obj files
  • featureSeeds: write information about explicit feature edge refinement
  • attraction: write attraction as .obj files
  • layerInfo: write information about layers

Example

debugFlags
(
    featureSeeds
    attraction
);

writeFlags (List) OPTIONAL​

Provides fine-grain control over the write output, including:

  • mesh: write all mesh information
  • noRefinement: write mesh without refinement information (level0Edges, surfaceIndex)
  • scalarLevels: write volScalarField with cellLevel for post-processing
  • layerSets: write cellSets, faceSets of faces in layer
  • layerFields: write a volScalarField for layer coverage

Example

writeFlags
(
    scalarLevels
    layerSets
    layerFields     // write volScalarField for layer coverage
);
