Detailed Description

Adds two meshes without using any polyMesh morphing.

Gets faces to couple as faceCoupleInfo which is list of faces on both meshes. Returns map from last mesh addition.

Find topologically and geometrically shared points.

  • should only be called for parallel correct mesh (since uses mesh.globalData)
  • returns Map from point to master point (all in mesh point labels) for any sets of points that need to be merged.

Old: geometric merging. Causes problems for two close shared points.

labelList sharedToMerged; label nUnique = Foam::mergePoints ( pointField ( mesh.points(), sharedPointLabels ), mergeDist, false, sharedToMerged );

Find out which sets of points get merged and create a map from mesh point to unique point.

Map<label> pointToMaster(10*sharedToMerged.size());

if (nUnique < sharedPointLabels.size()) { labelListList mergeSets ( invertOneToMany ( sharedToMerged.size(), sharedToMerged ) );

label nMergeSets = 0;

forAll(mergeSets, setI) { const labelList& mergeSet = mergeSets[setI];

if (mergeSet.size() > 1) { Take as master the shared point with the lowest mesh point label. (rather arbitrarily - could use max or any other one of the points)

nMergeSets++;

label masterI = labelMax;

forAll(mergeSet, i) { label sharedI = mergeSet[i];

masterI = min(masterI, sharedPointLabels[sharedI]); }

forAll(mergeSet, i) { label sharedI = mergeSet[i];

pointToMaster.insert(sharedPointLabels[sharedI], masterI); } } }

if (debug) { Pout<< "polyMeshAdder : merging:" << pointToMaster.size() << " into " << nMergeSets << " sets." << endl; } }

Helper: Merge points.

  • Gets map from point to destination point
  • Removes all points that don't map to themselves
  • Modifies all faces that use the points to be removed.
