Struct PolyMesh 

pub struct PolyMesh {
    pub points: Vec<Vector3>,
    pub faces: Vec<MeshFace>,
    pub n_internal_faces: usize,
    pub n_cells: usize,
    pub patches: Vec<BoundaryPatch>,
}

A connectivity-carrying poly-mesh — the on-disk polyMesh representation.

Faces are ordered internal-first ([0, n_internal_faces)), then boundary faces grouped by patch, matching OpenFOAM. Call PolyMesh::to_fv_mesh to obtain the geometry-carrying FvMesh.

Fields

points: Vec<Vector3>

Mesh points [m].

faces: Vec<MeshFace>

All faces, internal first then boundary.

n_internal_faces: usize

Number of internal faces (leading internal entries in faces).

n_cells: usize

Number of cells.

patches: Vec<BoundaryPatch>

Boundary patches, covering [n_internal_faces, faces.len()).

Implementations

impl PolyMesh

pub fn n_points(&self) -> usize

Number of points.

pub fn n_faces(&self) -> usize

Total number of faces (internal + boundary).

pub fn n_boundary_faces(&self) -> usize

Number of boundary faces.

pub fn total_volume(&self) -> f64

Total mesh volume [m^3] — the sum of all cell volumes.

pub fn to_fv_mesh(&self) -> Result<FvMesh, IoError>

Convert to the geometry-carrying FvMesh, computing cell volumes/centres, face-area vectors, face areas, and face centres from the point/face topology.

Errors

IoError::Mesh if the assembled mesh fails FvMesh::validate.

pub fn read(dir: impl AsRef<Path>) -> Result<Self, IoError>

Read a polyMesh from a constant/polyMesh directory.

Reads points, faces, owner, neighbour, and boundary.

pub fn write(&self, dir: impl AsRef<Path>) -> Result<(), IoError>

Write the polyMesh files into dir, creating it if necessary.
