fvModels: Specify source property values in field files
When an fvModel source introduces fluid into a simulation it should also
create a corresponding source term for all properties transported into
the domain by that injection. The source is, effectively, an alternative
form of inlet boundary, on which all transported properties need an
inlet value specified.
These values are now specified in the property field files. The
following is an example of a 0/U file in which the velocity of fluid
introduced by a fvModel source called "injection1" is set to a fixed
value of (-1 0 0):
dimensions [0 1 -1 0 0 0 0];
internalField uniform (0 0 0);
boundaryField
{
#includeEtc "caseDicts/setConstraintTypes"
wall
{
type noSlip;
}
atmosphere
{
type pressureInletOutletVelocity;
value $internalField;
}
}
// *** NEW ***
sources
{
injection1
{
type uniformFixedValue;
uniformValue (-1 0 0);
}
}
And the following entry in the 0/k file specifies the turbulent kinetic
energy introduced as a fraction of the mean flow kinetic energy:
sources
{
injection1
{
type turbulentIntensityKineticEnergy;
intensity 0.05;
}
}
The specification is directly analogous to boundary conditions. The
conditions are run-time selectable and can be concisely implemented.
They can access each other and be inter-dependent (e.g., the above,
where turbulent kinetic energy depends on velocity). The syntax keeps
field data localised and makes the source model (e.g., massSource,
volumeSource, ...) specification independent from what other models and
fields are present in the simulation. The 'fieldValues' entry previously
required by source models is now no longer required.
If source values need specifying and no source condition has been
supplied in the relevant field file then an error will be generated.
This error is similar to that generated for missing boundary conditions.
This replaces the behaviour where sources such as these would introduce
a value of zero, either silently or with a warning. This is now
considered unacceptable. Zero might be a tolerable default for certain
fields (U, k), but is wholly inappropriate for others (T, epsilon, rho).
This change additionally makes it possible to inject fluid into a
multicomponent solver with a specified temperature. Previously, it was
not possible to do this as there was no means of evaluating the energy
of fluid with the injected composition.

multiphaseEuler: New implicit drag algorithm replaces partial-elimination corrector
The momentum equation central coefficient and drag matrix is formulated, inverted and used to eliminate the drag terms from each of the phase momentum equations which are combined for formulate a drag-implicit pressure equation. This eliminates the lagged drag terms from the previous formulation which significantly improves convergence for small particle and Euler-VoF high-drag cases. It would also be possible to refactor the virtual-mass terms and include the central coefficients of the phase acceleration terms in the drag matrix before inversion to further improve the implicitness of the phase momentum-pressure coupling for bubbly flows. This work is pending funding. |

Modular solvers: Reorganised directory structure of applications and tutorials
The new flexible and extensible modular solvers structure already provides most
of the simulation functionality needed for single phase, multiphase,
multicomponent etc. fluid flow problems as well as a very effective method of
combining these with solid heat transfer, solid stress, surface film to solve
complex multi-region, multi-physics problems and are now the primary mechanism
for the further development of OpenFOAM simulation capability in future. To
emphasis this for both users and developers the applications/solvers directory
has been separated into applications/modules containing all the solver modules:
├── modules
│ ├── compressibleMultiphaseVoF
│ ├── compressibleVoF
│ ├── film
│ ├── fluid
│ ├── fluidSolver
│ ├── functions
│ ├── incompressibleDenseParticleFluid

│ ├── twoPhaseSolver
│ ├── twoPhaseVoFSolver

│ └── XiFluid
applications/solvers containing the foamRun and foamMultiRun solver applications
which instantiate and execute the chosen solver modules and also standalone
solver applications for special initialisation and test activities:
├── solvers
│ ├── boundaryFoam
│ ├── chemFoam
│ ├── foamMultiRun
│ ├── foamRun
│ └── potentialFoam
and applications/legacy containing legacy solver applications which are not
currently being actively developed but the functionality of which will be merged
into the solver modules or form the basis of new solver modules as the need
arises:

│ │ └── shallowWaterFoam
│ └── lagrangian

│ ├── mdEquilibrationFoam

Correspondingly the tutorials directory structure has been reorganised with the
modular solver directories at the top level with names that make it easier for
users to find example cases relating to their particular requirements and a
legacy sub-directory containing cases corresponding to the legacy solver
applications listed above:
