When more than one volumetric B-Splines control boxes are present, the
sensitivity constituents corresponding to the non-active design
variables were not bounded(zeroed) correctly. The resultant
sensitivities, used in the optimization, were bounded correctly, so this
was more a bug pertaining to the output file of the sensitivities rather
than a functional one.
- previously the store() method just set the ownedByRegistry flag.
Now ensure that it is indeed registered first.
- support register/store of tmp<> items.
The tmp parameter is not cleared, but changed from PTR to CREF
to allow further use.
The implicit registration allows code simplification using the
GeometricField::New factory method, for example.
Old Code
========
volScalarField* ptr = new volScalarField
(
IOobject
(
fieldName,
mesh.time().timeName(),
mesh,
IOobject::NO_READ,
IOobject::NO_WRITE,
true // Register
),
mesh,
dimless,
zeroGradientFvPatchField<scalar>::typeName
);
ptr->store();
New Code
========
auto tptr = volScalarField::New
(
fieldName,
mesh,
dimless,
zeroGradientFvPatchField<scalar>::typeName
);
regIOobject::store(tptr);
or even
regIOobject::store
(
volScalarField::New
(
fieldName,
mesh,
dimless,
zeroGradientFvPatchField<scalar>::typeName
)
);
The collated container ('decomposedBlockData') is always binary
but the 'payload' might be ascii so use that header information
instead of the decomposeBlockData header.
- kEpsilonPhitF is a kEpsilon-based model which originated
from (Durbin, 1995)’s v2-f methodology. However, the majority of
v2-f model variants proved to be numerically stiff for segregated
solution algorithms due to the coupled formulations of v2 and f fields,
particularly on wall boundaries.
The v2-f variant (i.e. OpenFOAM’s v2f model) due to
(Lien and Kalitzin, 2001) reformulated the original v2-f model to enable
segregated computations; however, a number of shortcomings regarding
the model fidelity were reported in the literature.
To overcome the shortcomings of the v2-f methodology, the v2-f approach
was re-evaluated by (Laurence et al., 2005) by transforming v2 scale into
its equivalent non-dimensional form, i.e. phit, to reduce the numerical
stiffness.
This variant, i.e. kEpsilonPhitF, is believed to provide numerical
robustness, and insensitivity to grid anomalies while retaining the
theoretical model fidelity of the original v2-f model.
Accordingly the v2f RANS model is deprecated in favour of the variant
kEpsilonPhitF model.
When activeDesignVariables are not set explicitly, all design variables
are treated as active. These were allocated properly when starting from
0 but not when starting from an intermediate optimisation cycle
(e.g. running 5 optimisation cycles, stopping and restarting).
TUT: added a new tutorial including the restart of an optimisation run
to help identify future regression
The controlBoxes wordList was removed from NURBS3DVolume in the
pre-release phase but writeMorpherCPs was not updated accordingly.
TUT: added the invocation of writeMorpherCPs in one of the tutotials to
help identify future regression
- The core of the FatalIOError message was not printed due to exiting
with FatalError instead of FatalIOError
- Changed the TypeName in all derived classes of displacementMethod so
that the toc printed by the FatalIOError corresponds to what the user
should add in dynamicMeshDict
When a contact resistance is used the T field on each coupled
patch is different due to the thermal resistance. Thus, instead
of solving for a unique Tw at the wall, we solve for Tw1 at one side
then, the Tnbr internal becomes Tw2, which is the T of the nbr
patch.

Many possibilities:
- use as a simple calculator with vectors, tensors etc.
- test validity of expression syntax
As a calculator:
foamCalc '(vector(1,2,3) ^ vector(4,5,6)) * sqrt(34)'
The same, but with debugging:
foamCalc -debug-switch fieldExpr=6 \
'mag((vector(1,2,3) ^ vector(4,5,6))) * sqrt(34)'
