Class containing mesh-to-mesh mapping information after a change in polyMesh topology. General: - pointMap/faceMap/cellMap: from current mesh back to previous mesh. (so to 'pull' the information onto the current mesh) - reversePointMap/faceMap/cellMap: from previous mesh to current. (so to 'push' information) In the topology change points/faces/cells - can be unchanged. (faces might be renumbered though) - can be removed. - can be added from existing same 'master' entity (so point from point, face from face and cell from cell) - can be inflated: face out of edge or point, cell out of face, edge or point. - can be appended: added 'out of nothing'. All this information is nessecary to correctly map fields. points ------ unchanged: pointMap[pointI] contains old point label reversePointMap[oldPointI] contains new point label removed: reversePointMap[oldPointI] contains -1 added-from-same: pointMap[pointI] contains the old master point label appended: pointMap[pointI] contains -1 faces ----- unchanged: faceMap[faceI] contains old face label reverseFaceMap[oldFaceI] contains new face label removed: reverseFaceMap[oldFaceI] contains -1 added-from-same: faceMap[faceI] contains the old master face label inflated-from-edge: faceMap[faceI] contains -1 facesFromEdges contains an entry with - faceI - list of faces(*) on old mesh that connected to the old edge inflated-from-point: faceMap[faceI] contains -1 facesFromPoints contains an entry with - faceI - list of faces(*) on old mesh that connected to the old point appended: faceMap[faceI] contains -1 *) if the newly inflated face is a boundary face the list of faces will only be boundary faces; if the new face is an internal face they will only be internal faces. cells ----- unchanged: cellMap[cellI] contains old cell label reverseCellMap[oldCellI] contains new cell label removed: reverseCellMap[oldCellI] contains -1 added-from-same: cellMap[cellI] contains the old master cell label inflated-from-face: cellMap[cellI] contains -1 cellsFromFaces contains an entry with - cellI - list of cells on old mesh that connected to the old face inflated-from-edge: cellMap[cellI] contains -1 cellsFromEdges contains an entry with - cellI - list of cells on old mesh that connected to the old edge inflated-from-point: cellMap[cellI] contains -1 cellsFromPoints contains an entry with - cellI - list of cells on old mesh that connected to the old point appended: cellMap[cellI] contains -1
