- similar to what erase() does, but as a mutable operation (#1180)
- replace basicThermo lookupAndCheckout (commit 880c98757d) with
the new objectRegistry::checkOut() method.
New name: findObject(), cfindObject()
Old name: lookupObjectPtr()
Return a const pointer or nullptr on failure.
New name: findObject()
Old name: --
Return a non-const pointer or nullptr on failure.
New name: getObjectPtr()
Old name: lookupObjectRefPtr()
Return a non-const pointer or nullptr on failure.
Can be called on a const object and it will perform a
const_cast.
- use these updated names and functionality in more places
NB: The older methods names are deprecated, but continue to be defined.
This allows single, multi-phase and VoF compressible simulations to be performed
with the accurate thermophysical property functions for liquids provided by the
liquidProperty classes. e.g. in the
multiphase/compressibleInterFoam/laminar/depthCharge2D tutorial water can now be
specified by
thermoType
{
type heRhoThermo;
mixture pureMixture;
properties liquid;
energy sensibleInternalEnergy;
}
mixture
{
H2O;
}
as an alternative to the previous less accurate representation defined by
thermoType
{
type heRhoThermo;
mixture pureMixture;
transport const;
thermo hConst;
equationOfState perfectFluid;
specie specie;
energy sensibleInternalEnergy;
}
mixture
{
specie
{
molWeight 18.0;
}
equationOfState
{
R 3000;
rho0 1027;
}
thermodynamics
{
Cp 4195;
Hf 0;
}
transport
{
mu 3.645e-4;
Pr 2.289;
}
}
However the increase in accuracy of the new simpler and more convenient
specification and representation comes at a cost: the NSRDS functions used by
the liquidProperties classes are relatively expensive to evaluate and the
depthCharge2D case takes ~14% longer to run.
These new names are more consistent and logical because:
primitiveField():
primitiveFieldRef():
Provides low-level access to the Field<Type> (primitive field)
without dimension or mesh-consistency checking. This should only be
used in the low-level functions where dimensional consistency is
ensured by careful programming and computational efficiency is
paramount.
internalField():
internalFieldRef():
Provides access to the DimensionedField<Type, GeoMesh> of values on
the internal mesh-type for which the GeometricField is defined and
supports dimension and checking and mesh-consistency checking.
When the GeometricBoundaryField template class was originally written it
was a separate class in the Foam namespace rather than a sub-class of
GeometricField as it is now. Without loss of clarity and simplifying
code which access the boundary field of GeometricFields it is better
that GeometricBoundaryField be renamed Boundary for consistency with the
new naming convention for the type of the dimensioned internal field:
Internal, see commit 4a57b9be2e
This is a very simple text substitution change which can be applied to
any code which compiles with the OpenFOAM-dev libraries.
To support these changes the need for "Sp" corrections on div-terms has been
eliminated by introducing a "bounded" convection scheme which subtracts the Sp
term from the selected scheme. The equivalent will be needed for the ddt term.
A warning message is generated for steady-state solvers in which the "bounded"
scheme is not selected for the convection terms.
New base class for fluid and solid thermo: veryBasicThermo
Base class for fluid thermo: basicThermo (derived from veryBasicThermo)
Base class for solid thermo: solidThermo (derived from veryBasicThermo)
Note in next commit basicThermo -> fluidThermo, veryBasicThermo -> basicThermo
At the specie level:
hs = sensible enthalpy
ha = absolute (what was total) enthalpy
es = sensibly internal energy
ea = absolute (what was total) internal energy
At top-level
Rename total enthalpy h -> ha
Rename sensible enthalpy hs -> h
Combined h, hs, e and es thermo packages into a single structure.
Thermo packages now provide "he" function which may return either enthalpy or
internal energy, sensible or absolute according to the run-time selected form
alphaEff now returns the effective diffusivity for the particular energy which
the thermodynamics package is selected to solve for.
- Added chemical enthalpy access function to top level api.
- Re-worked source term for enthalpy equation(s) in chemistry model, and
- Re-worked heat release calculation
STYLE: Using worded dimensions instead of dimensionSet(...)
