- use FACE_DATA (was SURFACE_DATA) for similarity with polySurface
ENH: add expression value enumerations and traits
- simple enumeration of standard types (bool, label, scalar, vector)
that can be used as a value type-code for internal bookkeeping.
GIT: relocate pTraits into general traits/ directory
- snGrad, internalField, neighbourField.
Functional use as per swak: "... + internalField(T) ..."
ENH: additional volume/patch expressions
- deltaT()
STYLE: rename exprDriverWriter -> fvExprDriverWriter
- the original class name was a misnomer since it holds a reference
to fvExprDriver
BUG: expression faceToPoint/pointToFace definitions were flipped
ENH: refactor expression hierarchy and code style
- handle TimeState reference at the top-level for simpler derivations
- unified internal search parameters (cruft)
- replaces previous code that used an autoPtr to hold a singleton.
In some circumstances this deletion would conflict with clearing
the objectRegistry - leading to error messages on exit.
Now store directly on the registry (similar to a MeshObject)
- use refPtr to simplify some logic.
- avoid copying field if an average will be used
- initialize geometric fields with a uniform value instead of Zero
- minor tweak of method names
- apply bugfix #1889 (longer description elsewhere)
- some support for "uniform" bool fields. Calculating an averaged
value for a boolField does not work very well, but we simply define
that the field average is 'true' when more than 1/2 of its values
are true. Not exactly true, but allows templated definitions to work
smoothly.
- additional output method writeValue().
This outputs the single (uniform) value or the first value of the
field.
