for consistency with reactingTwoPhaseEulerFoam and to ensure correct operation
of models requiring formal boundedness of phase-fractions.

Added a grow time and better allocate the CPU time to either add or grow. This
gives much more information to the user and helps changing the settings
accordingly.

"pos" now returns 1 if the argument is greater than 0, otherwise it returns 0.
This is consistent with the common mathematical definition of the "pos" function:
https://en.wikipedia.org/wiki/Sign_(mathematics)
However the previous implementation in which 1 was also returned for a 0
argument is useful in many situations so the "pos0" has been added which returns
1 if the argument is greater or equal to 0. Additionally the "neg0" has been
added which returns 1 if if the argument is less than or equal to 0.
Temporal variation of Ta is generally more useful than spatial variation but
a run-time switch between the two modes of operation could be implemented in
needed.
Initially the listSwitches functions depended directly on argList functionality
but this has now been factored out so that the listSwitches functions are more
general and require only debug functionality.
Provides better context for the available boundary conditions, fvOptions,
functionObjects etc. and thus returns only those available to and compatible
with the particular application.

Further work will be needed to support the -listTurbulenceModels option in
multiphase solvers.
The calculation of the max and min limits are now only performed if required,
i.e. specified in fvSolution.

This addition allows for theoretical wave models to be utilised for
initialisation and as boundary conditions. Multiple models can be used
simultaneously, each with differing phases and orientations. If multiple
models are used the shapes and velocities are superimposed.
The wave models are specified in the velocity boundary condition. The
phase fraction boundary condition and the set utility both look up the
velocity condition in order to access the wave model. A velocity
boundary may be specified as follows:
inlet
{
type waveVelocity;
origin (0 0 0);
direction (1 0 0);
speed 2;
waves
(
Airy
{
length 300;
amplitude 2.5;
depth 150;
phase 0;
angle 0;
}
);
scale table ((1200 1) (1800 0));
crossScale constant 1;
}
The alpha boundary only requires the type, unless the name of the
velocity field is non-standard, in which case a "U" entry will also be
needed. The setWaves utility does not require a dictionary file; non-
standard field names can be specified as command-line arguments.
Wave models currently available are Airy (1st order) and Stokes2 (second
order). If a depth is specified, and it is not too large, then shallow
terms will be included, otherwise the models assume that the liquid is
deep.
This work was supported by Jan Kaufmann and Jan Oberhagemann at DNV GL.
This function object reports the height of the interface above a set of
locations. It writes the height above the location, above the boundary,
and the point on the interface. It uses an integral approach, so if
there are multiple interfaces above or below a location, this method
will compute an average.
It can be enabled with the following entry in the system/controlDict:
functions
{
interfaceHeight1
{
type interfaceHeight;
libs ("libfieldFunctionObjects.so");
alpha alpha.water;
locations ((0 0 0) (10 0 0) (20 0 0));
}
}

This fvOption applies an explicit damping force to components of the
vector field in the direction of gravity. Its intended purpose is to
damp the vertical motions of an interface in the region approaching an
outlet so that no reflections are generated. The level of damping is
specified by a coefficient, lambda, given in units of 1/s.
It can be enabled for a cellZone named "nearOutlet", by adding the
following entry to constant/fvOptions:
verticalDamping1
{
type verticalDamping;
selectionMode cellZone;
cellZone nearOutlet;
lambda [0 0 -1 0 0 0 0] 1;
timeStart 0;
duration 1e6;
}

Now the "localEuler" ddt scheme does not apply any corrections due to
mesh-motion; the old-time volumes are not used and the mesh-motion flux is set
to zero. A consequence of these changes is that boundedness of transported
scalars is ensured but mesh-motion causes a conservation error which will
reduces to zero as steady-state is approached and the mesh becomes stationary.
vectorField or vector2DField from scalarField components. To do this
properly and have it work for field-type combinations would require some
new field function macros.
discontinuous fields, with the discontinuity defined by a level set. The
functions do a proper integration of the discontinuous fields by tet-
and tri-cutting along the plane of the level set.
now possible with level-sets as well as planes. Removed tetPoints class
as this wasn't really used anywhere except for the old tet-cutting
routines. Restored tetPointRef.H to be consistent with other primitive
shapes. Re-wrote tet-overlap mapping in terms of the new cutting.
See tutorials/compressible/rhoPimpleFoam/RAS/squareBendLiq for exapmle
pimpleControl: Added SIMPLErho option for running in SIMPLE mode
with large time-step/Courant number and relaxation. With this option the
density is updated from thermodynamics rather than continuity after the pressure
equation which is better behaved if pressure is relaxed and/or solved to a
loose relative tolerance. The need for this option is demonstrated in the
tutorials/compressible/rhoPimpleFoam/RAS/angledDuct tutorial which is unstable
without the option.
In addition to local Doxygen HTML directories an optional HTTP server directory
may be specified:
Documentation
{
docBrowser "firefox";
doxyDocDirs
(
"$WM_PROJECT_USER_DIR/html"
"~OpenFOAM/html"
"$WM_PROJECT_DIR/doc/Doxygen/html"
"http://cpp.openfoam.org/dev"
);
doxySourceFileExt "_8C.html";
}
from which the Doxygen documentation files may be obtained so now the "-doc"
command-line option may be used even if if Doxygen has not been run locally,
e.g.
pimpleFoam -doc
