Detailed Description

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)

  1. Perfect match:
    • one-to-one match for faces and points.
    • the cut is always the 'most connected' of the master and slave so multiple master or slave points might point to the same cut point.
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.

  1. Subdivision match:
    • Can be constructed from slave being subdivision of master with the polyPatch constructor.
    • Does not include above shared-point detection!

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)

Constructor & Destructor Documentation

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.

Here is the call graph for this function:

faceCoupleInfo ( const polyMesh masterMesh,
const labelList masterAddressing,
const polyMesh slaveMesh,
const labelList slaveAddressing,
const scalar  absTol,
const bool  perfectMatch,
const bool  orderedFaces,
const bool  patchDivision 
)

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.
