The PIMPLE option finalOnLastPimpleIterOnly allows the call the Final
solver only in the last PIMPLE loop. The default is false which is
the present behavior.
ENH: add generalised log-law type ground-normal inflow boundary conditions for

dry-air, equilibrium and neutral atmospheric boundary layer (ABL) modelling

ENH: add a verification case for atmBoundaryLayerInlet BCs
DOC: improve atmBoundaryLayerInlet header documentation
BUG: fix value-entry behaviour in atmBoundaryLayerInlet (fixes#1578)
Without this change:
- for serial-parallel computations, if `value` entry is available in
an `atmBoundaryLayerInlet` BC, the theoretical ABL profile expressions
are not computed, and the `value` entry content is used as a profile data
- for parallel computations, if `value` entry is not available, `decomposePar`
could not be executed.
With this change:
- assuming `value` entry is always be present, the use of `value` entry for
the ABL profile specification is determined by a flag `initABL`
- the default value of the optional flag `initABL` is `true`, but whenever
`initABL=true` is executed, `initABL` is overwritten as `false` for the
subsequent runs, so that `value` entry can be safely used.
Thanks Per Jørgensen for the bug report.
BUG: ensure atmBoundaryInlet conditions are Galilean-invariant (fixes#1692)

TUT: update simpleFoam/turbineSiting tutorial accordingly
STDMD (i.e. Streaming Total Dynamic Mode Decomposition) is a variant of
a data-driven dimensionality reduction method.
STDMD is being used as a mathematical post-processing tool to compute
a set of dominant modes out of a given flow (or dataset) each of which is
associated with a constant frequency and decay rate, so that dynamic
features of a given flow may become interpretable, and tractable.
Among other Dynamic Mode Decomposition (DMD) variants, STDMD is presumed
to provide the general DMD method capabilities alongside economised and
feasible memory and CPU usage.
Please refer to the header file documentation for further details.
ENH: add new STDMD tutorial, pimpleFoam/laminar/cylinder2D
The phase systems tables for multiphase solvers create conflict
between each other as they are defined in the same namespace and using
similar class names.
Therefore a special htc function object for reactingEulerSolver was
added (reactingEulerHtcModel), located under
src/phaseSystemModels/reactingEulerFoam/functionObjects/
This commit includes the following:
- Relocate solvers/reactingEulerFoam functionObjects to
src/phaseSystemModels
- Remove links for fieldFunctionObject to multiphase libs to avoid
conflicts
- New FO for htc for reactingEulerFoam called reactingEulerHtcModel
The final leak can only be decided once all cells have been
deleted. So only exit on final invocation and give warning-only
beforehand. This avoids a lot of false positives.
The tutorial itself didn't actually produce a mesh with leakage
with the old settings. Upped the refinement level to force it
to go through the hole in the geometry.
- enumerated values are (points | topology) which can be optionally
specified in the blockMeshDict. Default is 'topology'.
If the command-line option `blockMesh -merge-points` is specified,
this has absolute priority over any blockMeshDict entry.
STYLE: changed blockMesh "-blockTopology" option to "-write-obj"
- this is more specific to what it does. Potentially wish to add a
"-write-vtk" option in the future.
TUT: adjust tutorials to use preferred or necessary merge strategies:
* channel395DFSEM - topology
* nozzleFlow2D - points
* pipeCyclic - points
For a given point within a given mesh, the existing `meshWave` method gives
the orthogonal distance to a patch. In meshes with very steep terrain (e.g.
a hill of 90 [deg], this might be problematic for the fields that require
the distance to the patch associated with the terrain surface.
`directionalMeshWave` is a variant of `meshWave` distance-to-patch method,
which ignores the component in the specified direction. Can be used e.g. to
calculate the distance in the z-direction only.
TUT: add example of directionalMeshWave to mesh/moveDynamicMesh/SnakeCanyon
Requirement by CENER
Implementation by Mattijs Janssens
- bin/tools/create-mpi-config to query/write values for system openmpi.
In some cases this can be used to avoid an mpicc requirement at runtime.
- adjust openfoam session to include -test-tutorial forwarding to the
tutorials/AutoTest. This helps with writing installation tests.
- adjust foamConfigurePaths to latest version
- removal of gperftools default config, as per develop
1) Add interfaceHeatResistance model to icoReactingMultiphaseInterFoam
This model uses a spread source for the continuity Eq.
It is recommended for cases with good mesh resolution.
2) Adding iso-surface type of calculation for the interface for
the kineticGasEvaporation model
3) Add switch for option to take into account volume change
4) Add poolEvaporation tutorial
Now the thermal baffle can be extrapolated from a patch which is
coupled to the bottom patch of the solid region.
The user can set the T bc on the 'top' patch of the solid.
The new keyword is 'internal' and its default is true. Check new
tutorial for an example:
tutorials/heatTransfer/buoyantSimpleFoam/roomWithThickCeiling/
- base level surface container is now a meshedSurface instead of
a triSurface. This avoid automatic triangulation of surfaces
when they are read, and simplifies the internals.
- sampling types:
* "meshedSurface" (compat: "sampledTriSurfaceMesh")
* "meshedSurfaceNormal" (compat: "sampledTriSurfaceMeshNormal")
- string expansions have supported "${var:-default}" syntax for
several versions, but this did not apply plain dictionary expansions.
Eg, the following did not parse
massFlow ${entry1:-100};
ENH: remove content and length restriction on '${..}' quoted variables
- allows this type of content:
velocity2 ${velocity1:- ( 0 -100 10) };
- accept empty parameter strings for entries. This allows the
following expansion to work as expected:
hex (n1 n2..) ${inletBlock:-} (10 10 10) simpleGrading (1 1 1)
ie, optionally define the cellZone name for a given block
ENH: add single parameter dictionary writeEntry method.
- the dictionary knows its own name (dictName), which can be used
when writing content
1) Adding interfaceHeight FO
2) Adding interfaceHeatResistance mass transfer model to
interCondensatingEvaporatingFoam with spread source approach
3) Reworking framework for icoReactingMultiphaseInterFoam
- includes restructuring and simplification of low-level ensight part
handling and refactor of backends to improve code reuse.
foamToEnsight
-------------
* new cellZone support.
This was previously only possible via a separate foamToEnsightParts
utility that was not parallelized.
* support for point fields.
* `-nearCellValue` option (as per foamToVTK)
* data indexing now uses values from the time index.
This is consistent with the ensightWrite function object and
can help with restarts.
* existing ensight directories are removed, unless the -no-overwrite
option is supplied
foamToEnsightParts
------------------
* now redundant and removed.
ensightOutputSurface (new class)
--------------------------------
* a lightweight wrapper for point/face references that is tailored
for the ensightSurfaceWriter. It uses compact face/point information
and is serial only, since this is the format requirements from the
surfaceWriter class.
ensightMesh (revised class)
---------------------------
* now only holds a polyMesh reference, which removes its dependency
on finiteVolume and allows it to be relocated under fileFormats
instead of conversion.
Removed classes: ensightParts, ensighPartFaces, ensightPartCells
- these were used by foamToEnsightParts, but not needed anymore.
