Struct AmiCoupling 

pub struct AmiCoupling {
    pub target_face: usize,
    pub target_cell: usize,
    pub target_patch: usize,
    pub source_patch: usize,
    pub local: usize,
    pub weights: Vec<AmiWeight>,
}

One target seam face of a PatchKind::CyclicAmi patch pair, together with the weighted set of source cells it couples to.

Mirrors the coupled-interface contribution of Foam::cyclicAMIFvPatchField whose patchNeighbourField() supplies the interpolated partner value Σ_k w_k · φ(source_cell_k).

The couplings are appended to the LDU face addressing after the internal faces and the CyclicCouplings: one LDU face per AmiWeight, laid out in ami_couplings order (see FvMesh::ami_ldu_start and FvMesh::n_ami_faces).

Fields

target_face: usize

Global face index of this target seam face.

target_cell: usize

Owner cell of the target face — the “owner” side of every partial seam face in weights.

target_patch: usize

Patch index of the target half of the AMI pair.

source_patch: usize

Patch index of the source half of the AMI pair.

local: usize

Local face index of the target face within its patch (target_face - patches[target_patch].start).

weights: Vec<AmiWeight>

Weighted source contributions; per-target weights sum to ≈ 1.

Implementations

impl AmiCoupling

pub fn weight_sum(&self) -> f64

Sum of this target’s overlap weights. Equals 1 (to rounding) when the target face is fully covered by source faces — the conservation check.
