Functions

bool visNormal (const vector &n, const vectorField &faceNormals, const labelList &faceLabels)
 Check if n is in same direction as normals of all faceLabels.
vectorField calcBoxPointNormals (const primitivePatch &pp)
 Calculate point normals on a 'box' mesh (all edges aligned with.
vector normEdgeVec (const primitiveMesh &, const label edgeI)
 Normalized edge vector.
void writeOBJ (Ostream &os, const point &pt)
 Write obj representation of point.
void writeOBJ (Ostream &os, const faceList &, const pointField &, const labelList &faceLabels)
 Write obj representation of faces subset.
void writeOBJ (Ostream &os, const faceList &, const pointField &)
 Write obj representation of faces.
void writeOBJ (Ostream &os, const cellList &, const faceList &, const pointField &, const labelList &cellLabels)
 Write obj representation of cell subset.
bool edgeOnCell (const primitiveMesh &, const label cellI, const label edgeI)
 Is edge used by cell.
bool edgeOnFace (const primitiveMesh &, const label faceI, const label edgeI)
 Is edge used by face.
bool faceOnCell (const primitiveMesh &, const label cellI, const label faceI)
 Is face used by cell.
label findEdge (const edgeList &edges, const labelList &candidates, const label v0, const label v1)
 Return edge among candidates that uses the two vertices.
label findEdge (const primitiveMesh &, const label v0, const label v1)
 Return edge between two vertices. Returns -1 if no edge.
label getSharedEdge (const primitiveMesh &, const label f0, const label f1)
 Return edge shared by two faces. Throws error if no edge found.
label getSharedFace (const primitiveMesh &, const label cell0, const label cell1)
 Return face shared by two cells. Throws error if none found.
void getEdgeFaces (const primitiveMesh &, const label cellI, const label edgeI, label &face0, label &face1)
 Get faces on cell using edgeI. Throws error if no two found.
label otherEdge (const primitiveMesh &, const labelList &edgeLabels, const label edgeI, const label vertI)
 Return label of other edge (out of candidates edgeLabels)
label otherFace (const primitiveMesh &, const label cellI, const label faceI, const label edgeI)
 Return face on cell using edgeI but not faceI. Throws error.
label otherCell (const primitiveMesh &, const label cellI, const label faceI)
 Return cell on other side of face. Throws error.
label walkFace (const primitiveMesh &, const label faceI, const label startEdgeI, const label startVertI, const label nEdges)
 Returns label of edge nEdges away from startEdge (in the direction.
void constrainToMeshCentre (const polyMesh &mesh, point &pt)

label cutDirToEdge (const primitiveMesh &, const label cellI, const vector &cutDir)
 Reverse of edgeToCutDir: given direction find edge bundle and.
