Automatic hole closure:
- introduces 'holeToFace' topoSet source
- used when detecting a 'leak-path'
- creates additional baffles to close the leak
Multi-stage layer addition:
- Can add layers in multiple passes
See issues: #2403, #2404
This is for a very specific use case where the faceZones are
imprinted after meshing the normal geometry. This sometimes
splits off badly connected bits of the mesh. One way to remove
these is to use e.g. subsetMesh. This embeds the
same functionality inside snappyHexMesh.
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
- use the dictionary 'get' methods instead of readScalar for
additional checking
Unchecked: readScalar(dict.lookup("key"));
Checked: dict.get<scalar>("key");
- In templated classes that also inherit from a dictionary, an additional
'template' keyword will be required. Eg,
this->coeffsDict().template get<scalar>("key");
For this common use case, the predefined getXXX shortcuts may be
useful. Eg,
this->coeffsDict().getScalar("key");
- in 2.4.x the general default for polyMesh::findCell was FACE_DIAG_TRIS,
but this was changed to CELL_TETS for better handling of concave
cells.
- in snappyHexMesh meshRefinement, findCell is used to define
locations in mesh and cells for closer refinement. Using CELL_TETS
causes an octree rebuild when the mesh has changed and this adds
considerable overhead. For this operation, the faster FACE_DIAG_TRIS
mode can be used instead.
- in many cases can just use lookupOrDefault("key", bool) instead of
lookupOrDefault<bool> or lookupOrDefault<Switch> since reading a
bool from an Istream uses the Switch(Istream&) anyhow
STYLE: relocated Switch string names into file-local scope
