Now faceZones are handled directly by the applications and the new
faceZone::topoChange function so that any face can now be in any number of
zones, significantly increasing the flexibility and usefulness of faceZones.
This completes the generalisation of cellZone, faceZone and pointZone to support
multiple zones for each cell, face or point respectively. Next step will be to
make zones polymorphic and run-time selectable so that they can alter during the
run and adapt to moving meshes for example.
The concept of cell and face inflation proved unworkable in general and has been
replaced by the more flexible and robust cell-splitting combined with
conservative interpolative mapping and mesh morphing as appropriate.
The timeName() function simply returns the dimensionedScalar::name() which holds
the user-time name of the current time and now that timeName() is no longer
virtual the dimensionedScalar::name() can be called directly. The timeName()
function implementation is maintained for backward-compatibility.
This new mapping structure is designed to support run-time mesh-to-mesh mapping
to allow arbitrary changes to the mesh structure, for example during extreme
motion requiring significant topology change including region disconnection etc.
The polyTopoChangeMap is the map specifically relating to polyMesh topological
changes generated by polyTopoChange and used to update and map mesh related
types and fields following the topo-change.
splitBaffles identifies baffle faces; i.e., faces on the mesh boundary
which share the exact same set of points as another boundary face. It
then splits the points to convert these faces into completely separate
boundary patches. This functionality was previously provided by calling
mergeOrSplitBaffles with the "-split" option.
mergeBaffles also identifes the duplicate baffle faces, but then merges
them, converting them into a single set of internal faces. This
functionality was previously provided by calling mergeOrSplitBaffles
without the "-split" option.
