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.
- 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.

- 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.
