The mergePatchPairs functionality in blockMesh also now uses patchIntersection.
The new mergePatchPairs and patchIntersection replaces the old, fragile and
practically unusable polyTopoChanger::slidingInterface functionality the removal
of which has allowed the deletion of a lot of other ancient and otherwise unused
clutter including polyTopoChanger, polyMeshModifier, polyTopoChange::setAction
and associated addObject/*, modifyObject/* and removeObject/*. This
rationalisation paves the way for the completion of the update of zone handling
allowing mesh points, faces and cells to exist in multiple zones which is
currently not supported with mesh topology change.
Application
stitchMesh
Description
Utility to stitch or conform pairs of patches,
converting the patch faces either into internal faces
or conformal faces or another patch.
Usage
\b stitchMesh (\<list of patch pairs\>)
E.g. to stitch patches \c top1 to \c top2 and \c bottom1 to \c bottom2
stitchMesh "((top1 top2) (bottom1 bottom2))"
Options:
- \par -overwrite \n
Replace the old mesh with the new one, rather than writing the new one
into a separate time directory
- \par -region \<name\>
Specify an alternative mesh region.
- \par -fields
Update vol and point fields
- \par -tol
Merge tolerance relative to local edge length (default 1e-4)
