Description
Transforms the specified velocity field into a
cylindrical polar coordinate system or back to Cartesian.
Example of function object specification to convert the velocity field U
into cylindrical polar coordinates before averaging and returning the
average to Cartesian coordinates:
\verbatim
cartesianToCylindrical
{
type cylindrical;
libs ("libfieldFunctionObjects.so");
origin (0 0 0);
axis (0 0 1);
field U;
writeControl outputTime;
writeInterval 1;
}
#includeFunc fieldAverage(cylindrical(U))
cylindricalToCartesian
{
type cylindrical;
libs ("libfieldFunctionObjects.so");
origin (0 0 0);
axis (0 0 1);
field cylindrical(U)Mean;
toCartesian true;
result UMean;
writeControl outputTime;
writeInterval 1;
}
\endverbatim
This is particularly useful for cases with rotating regions, e.g. mixer
vessels with AMI.

Description
Updates the writeInterval as a Function1 of time.
Examples of function object specification:
\verbatim
setWriteInterval
{
type setWriteInterval;
libs ("libutilityFunctionObjects.so");
writeInterval table
(
(0 0.005)
(0.1 0.005)
(0.1001 0.01)
(0.2 0.01)
(0.2001 0.02)
);
}
\endverbatim
will cause results to be written every 0.005s between 0 and 0.1s, every
0.01s between 0.1 and 0.2s and every 0.02s thereafter.
In multi-specie systems the calculation of Cp and Cv is relatively expensive due
to the cost of mixing the coefficients of the specie thermo model, e.g. JANAF,
and it is significantly more efficient if these are calculated at the same time
as the rest of the thermo-physical properties following the energy solution.
Also the need for CpByCpv is also avoided by the specie thermo providing the
energy type in the form of a boolean 'enthalpy()' function which returns true if
the energy type is an enthalpy form.
This simplifies and standardises the handling of radiation in all solvers which
include an energy equation, all of which now support radiation via the
'radiation' fvOption which is selected in the constant/fvOption or
constant/<region>/fvOption file:
radiation
{
type radiation;
libs ("libradiationModels.so");
}
The radiation model, parameters, settings and sub-models are specified in the
'radiationProperties' file as before.
with frozenFlow set true in the PIMPLE sub-dictionary of fvSolution the p-U
system is not solved and the energy-composition system including reactions is
solved with the fixed flow.
This is used to set the directory name for the results of the functionObject, if
not specified a unique name is generated automatically from the function type
and argument list, e.g.
#includeFunc patchAverage(name=inlet, fields=(p U))
writes surfaceFieldValue.dat in postProcessing/patchAverage(name=inlet,fields=(pU))/0 and
#includeFunc patchAverage(funcName=inlet, name=inlet, fields=(p U))
writes surfaceFieldValue.dat in postProcessing/inlet/0.
Now if a case is restarted from an arbitrary time, for example one generated at
a premature stop condition, or with an increased writeInterval, the subsequent
time directories written are referenced to the original start time of the case
rather than the restart time.
cpp is no longer used to pre-process Make/files files allowing standard make '#'
syntax for comments, 'ifdef', 'ifndef' conditionals etc. This is make possible
by automatically pre-pending SOURCE += to each of the source file names in
Make/files.
The list of source files compile can be specified either as a simple list of
files in Make/files e.g.
# Note: fileMonitor assumes inotify by default. Compile with -DFOAM_USE_STAT
# to use stat (=timestamps) instead of inotify
fileMonitor.C
ifdef SunOS64
dummyPrintStack.C
else
printStack.C
endif
LIB = $(FOAM_LIBBIN)/libOSspecific
or
or directly as the SOURCE entry which is used in the Makefile:
SOURCE = \
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C \
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C \
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
In either form make syntax for comments and conditionals is supported.
so that it can be included directly into the wmake Makefile to allow full
support of gmake syntax, variables, functions etc.
The Make/files file handled in the same manner as the Make/options file if it
contains the SOURCE entry otherwise it is first processed by cpp for backward
compatibility.
The list of source files compile can now be specified either as a simple list of
files in Make/files e.g.
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
or directly as the SOURCE entry which is used in the Makefile:
SOURCE = \
adjointOutletPressure/adjointOutletPressureFvPatchScalarField.C \
adjointOutletVelocity/adjointOutletVelocityFvPatchVectorField.C \
adjointShapeOptimizationFoam.C
EXE = $(FOAM_APPBIN)/adjointShapeOptimizationFoam
In both cases the Make/files is first parsed by cpp to handle #if, #ifdef
etc. directives but in the latter form gmake directives like ifeq can be also be
used to optionally select files to compile, typically using
SOURCE += anotherFile.C
statements.
All thermophysicalFunctions, NSRDS, API and the fast uniform and non-uniform
tables have now been converted into the corresponding Function1<scalar> and
Function2<scalar> so that they can be used in other contexts, e.g. diffusion
coefficients for multi-component diffusion and in conjunction with other
Function1 and Function2s. This also enables 'coded' Function1 and Function2 to
be used for thermo-physical properties.
Now all run-time selectable functions are within a single general framework
improving usability and simplifying maintenance.
