meshSearch | ( | const polyMesh & | mesh, |
const treeBoundBox & | bb, | ||
const polyMesh::cellDecomposition | cellDecompMode = polyMesh::CELL_TETS |

) |
Construct with a custom bounding box.
Any mesh element outside bb will not be found. Up to user to ensure bb extends slightly beyond wanted elements.

Foam::label findCell | ( | const point & | location, |
const label | seedCelli = -1 , |

const bool | useTreeSearch = true |

) | const |
Find cell containing location.
If seed provided walks and falls back to linear/tree search. (so handles holes correctly)s Returns -1 if not in domain.

Foam::label findNearestBoundaryFace | ( | const point & | location, |
const label | seedFacei = -1 , |

) | const |
Find nearest boundary face.
If seed provided walks but then does not pass local minima in distance. Also does not jump from one connected region to the next.
