Owner and neighbour indices are a shorthand notation.
1 face fields
For equations involving a face field, the owner and neighbour indices are:
Where:
- A_{o} is the face owner (i.e. the volume cell designated as owner by the mesh);
- A_{n} is the face neighbour (i.e. the volume cell designated as neighbour by the mesh); and
- is a face field.
For example, the main equation in lduMatrix;;faceH is:
2 volume fields
For equations involving a volume field, the owner and neighbour indices are given by:
Where:
- A are matrix coefficients; and
- o and n are the owner and neighbour indices.
For example, the main equation in lduMatrix;;negSumDiag is:
