- Updated tutorial headers
- Added copyright note to isoAdvector src
- Removed outcommented code lines in interIsoFoam solver
- Removed all LTS from interIsoFoam since this is not currently supported
- Confirmed that discInConstantFlow gives identical results with N subCylces and time step N*dt
- Confirmed that this also holds when nOuterCorrectors > 1.
- the expansions were previously required as slash to follow, but
now either are possible.
"<case>", "<case>/" both yield the same as "$FOAM_CASE" and
will not have a trailing slash in the result. The expansion of
"$FOAM_CASE/" will however have a trailing slash.
- adjust additional files using these expansions
Support the following expansions when they occur at the start of a
string:
Short-form Equivalent
========= ===========
<etc>/ ~OpenFOAM/ (as per foamEtcFile)
<case>/ $FOAM_CASE/
<constant>/ $FOAM_CASE/constant/
<system>/ $FOAM_CASE/system/
These can be used in fileName expansions to improve clarity and reduce
some typing
"<constant>/reactions" vs "$FOAM_CASE/constant/reactions"
The combustion and chemistry models no longer select and own the
thermodynamic model; they hold a reference instead. The construction of
the combustion and chemistry models has been changed to require a
reference to the thermodyanmics, rather than the mesh and a phase name.
At the solver-level the thermo, turbulence and combustion models are now
selected in sequence. The cyclic dependency between the three models has
been resolved, and the raw-pointer based post-construction step for the
combustion model has been removed.
The old solver-level construction sequence (typically in createFields.H)
was as follows:
autoPtr<combustionModels::psiCombustionModel> combustion
(
combustionModels::psiCombustionModel::New(mesh)
);
psiReactionThermo& thermo = combustion->thermo();
// Create rho, U, phi, etc...
autoPtr<compressible::turbulenceModel> turbulence
(
compressible::turbulenceModel::New(rho, U, phi, thermo)
);
combustion->setTurbulence(*turbulence);
The new sequence is:
autoPtr<psiReactionThermo> thermo(psiReactionThermo::New(mesh));
// Create rho, U, phi, etc...
autoPtr<compressible::turbulenceModel> turbulence
(
compressible::turbulenceModel::New(rho, U, phi, *thermo)
);
autoPtr<combustionModels::psiCombustionModel> combustion
(
combustionModels::psiCombustionModel::New(*thermo, *turbulence)
);
ENH: combustionModel, chemistryModel: Simplified model selection
The combustion and chemistry model selection has been simplified so
that the user does not have to specify the form of the thermodynamics.
Examples of new combustion and chemistry entries are as follows:
In constant/combustionProperties:
combustionModel PaSR;
combustionModel FSD;
In constant/chemistryProperties:
chemistryType
{
solver ode;
method TDAC;
}
All the angle bracket parts of the model names (e.g.,
<psiThermoCombustion,gasHThermoPhysics>) have been removed as well as
the chemistryThermo entry.
The changes are mostly backward compatible. Only support for the
angle bracket form of chemistry solver names has been removed. Warnings
will print if some of the old entries are used, as the parts relating to
thermodynamics are now ignored.
ENH: combustionModel, chemistryModel: Simplified model selection
Updated all tutorials to the new format
STYLE: combustionModel: Namespace changes
Wrapped combustion model make macros in the Foam namespace and removed
combustion model namespace from the base classes. This fixes a namespace
specialisation bug in gcc 4.8. It is also somewhat less verbose in the
solvers.
This resolves bug report https://bugs.openfoam.org/view.php?id=2787
ENH: combustionModels: Default to the "none" model
When the constant/combustionProperties dictionary is missing, the solver
will now default to the "none" model. This is consistent with how
radiation models are selected.
and replaced interDyMFoam with a script which reports this change.
The interDyMFoam tutorials have been moved into the interFoam directory.
This change is one of a set of developments to merge dynamic mesh functionality
into the standard solvers to improve consistency, usability, flexibility and
maintainability of these solvers.

interMixingFoam, multiphaseInterFoam: Updated for changes to interFoam
Within decomposeParDict, it is now possible to specify a different
decomposition method, methods coefficients or number of subdomains
for each region individually.
The top-level numberOfSubdomains remains mandatory, since this
specifies the number of domains for the entire simulation.
The individual regions may use the same number or fewer domains.
Any optional method coefficients can be specified in a general
"coeffs" entry or a method-specific one, eg "metisCoeffs".
For multiLevel, only the method-specific "multiLevelCoeffs" dictionary
is used, and is also mandatory.
----
ENH: shortcut specification for multiLevel.
In addition to the longer dictionary form, it is also possible to
use a shorter notation for multiLevel decomposition when the same
decomposition method applies to each level.

ENH: compressibleInterFoam family: merged two-phase momentum stress modelling from compressibleInterPhaseTransportFoam
The new momentum stress model selector class
compressibleInterPhaseTransportModel is now used to select between the options:
Description
Transport model selection class for the compressibleInterFoam family of
solvers.
By default the standard mixture transport modelling approach is used in
which a single momentum stress model (laminar, non-Newtonian, LES or RAS) is
constructed for the mixture. However if the \c simulationType in
constant/turbulenceProperties is set to \c twoPhaseTransport the alternative
Euler-Euler two-phase transport modelling approach is used in which separate
stress models (laminar, non-Newtonian, LES or RAS) are instantiated for each
of the two phases allowing for different modeling for the phases.
Mixture and two-phase momentum stress modelling is now supported in
compressibleInterFoam, compressibleInterDyMFoam and compressibleInterFilmFoam.
The prototype compressibleInterPhaseTransportFoam solver is no longer needed and
has been removed.
- Arrhenius viscocity model for incompressible viscocity.

- Tutorial to show viscousDissipation:

In this version of compressibleInterFoam separate stress models (laminar,
non-Newtonian, LES or RAS) are instantiated for each of the two phases allowing
for completely different modeling for the phases.
e.g. in the climbingRod tutorial case provided a Newtonian laminar model is
instantiated for the air and a Maxwell non-Newtonian model is instantiated for
the viscoelastic liquid. To stabilize the Maxwell model in regions where the
liquid phase-fraction is 0 the new symmTensorPhaseLimitStabilization fvOption is
applied.
Other phase stress modeling combinations are also possible, e.g. the air may be
turbulent but the liquid laminar and an RAS or LES model applied to the air
only. However, to stabilize this combination a suitable fvOption would need to
be applied to the turbulence properties where the air phase-fraction is 0.
