Container for information needed to couple to meshes. When constructed from two meshes and a geometric tolerance finds the corresponding boundary faces.
The information it keeps is the set of faces&points (cutFaces, cutPoints) that should replace a set of faces on the master (masterPatch) and a set of faces on the slave (slavePatch)
Uses same tolerance to match faces and points on matched faces since they both originate from the same points and the tolerance usually comes from writing these points with limited precision (6 by default)
e.g. master: +--+ | | | | +--+ +--+ | | | | +--+ slave: +--+ | | | | +--+ +--+ | | | | +--+
adding both together creates a singly connected 2x2 cavity so suddenly the duplicate master points and the duplicate slave points all become a single cut point.
Notes on multiple slave faces per master:
As long as
So master: +-------+ | | | | | | | | | | | | | | +-------+ slave: +---+---+ |\ | /| | \ | / | | \|/ | +---+---+ | /|\ | | / | \ | |/ | \| +---+---+ is ok.
For this kind of matching the order is:
Note: matching refined faces onto master is a bit dodgy and will probably only work for unwarped faces. Also it will fail if e.g. face is split into 3x3 since then middle face has no point/edge in common with master. (problem is in face matching (findSlavesCoveringMaster), probably point/edge matching might just work)

faceCoupleInfo | ( | const polyMesh & | mesh0, |
const polyMesh & | mesh1, | ||
const scalar | absTol, | ||
const bool | perfectMatch | ||
) |
Construct from two meshes and absolute tolerance.
Finds out matches geometrically. No checking for nonsense match. Tolerance is absolute one so use with care. perfectMatch : each point/edge/face has corresponding point on other side if this is false then assumes slave is subdivision. Matching then will work only for non-warped faces since does nearest-to-face comparison with absTol.

Construct from meshes and subset of mesh faces.
(i.e. indirectPrimitivePatch addressing) All faces in patch are considered matched (but don't have to be ordered) perfectMatch : each point/edge/face has corresponding point on other side orderedFaces : faces in patch are ordered (so masterAddressing[i] matches slaveAddressing[i]) patchDivision: faces in slave mesh that originate from the same master face have the same patch. Used by some triangulation methods.
