Function1 is an abstract base-class of run-time selectable unary
functions which may be composed of other Function1's allowing the user
to specify complex functions of a single scalar variable, e.g. time.
The implementations need not be a simple or continuous functions;
interpolated tables and polynomials are also supported. In fact form of
mapping between a single scalar input and a single primitive type output
is supportable.
The primary application of Function1 is in time-varying boundary
conditions, it also used for other functions of time, e.g. injected mass
is spray simulations but is not limited to functions of time.
Description
Templated sine function with support for an offset level.
\f[
a sin(2 \pi f (t - t_0)) s + l
\f]
where
\vartable
a | Amplitude
f | Frequency [1/s]
s | Type scale factor
l | Type offset level
t_0 | Start time [s]
t | Time [s]
\endvartable
Example for a scalar:
\verbatim
<entryName> sine;
<entryName>Coeffs
{
frequency 10;
amplitude 0.1;
scale 2e-6;
level 2e-6;
}
\endverbatim
Example for a vector:
\verbatim
<entryName> sine;
<entryName>Coeffs
{
frequency 10;
amplitude 1;
scale (1 0.1 0);
level (10 1 0);
}
\endverbatim
PV4FoamReaders: Updated to build with ParaView-5.0.0
paraFoam: Updated to load PV4FoamReaders for ParaView-5.0.0
Currently this is experimental but if it becomes clear that ParaView-4
and ParaView-5 are and will remain consistent with respect to readers
the plan is to rename
PV4 -> PV
or
PV4 -> PV45 if it is assumed that PV6 may need to be different.
Removed inconsistent binary output.
Removed unused and IO-inconsistent functions.
Simplified the handling of backward-compatible constant value:
Removed the unnecessary CompatibilityConstant,
Updated Constant and DataEntryNew to handle constant value construction.
// Polynomial functions and interpolation do evaluate to label
// Instead evaluate a scalar and convert to label as appropriate
// makeDataEntryType(PolynomialEntry, label);
// makeDataEntryType(CSV, label);
// makeDataEntryType(Table, label);
// makeDataEntryType(TableFile, label);

If the mean velocity force is applied to a cyclic patch for parallel
runs include contributions from processorCyclic patches generated
from the decomposition of the cyclic patch
When restarting form a previous calculation, the averaging is continuous or
may be restarted using the \c restartOnRestart option.
The averaging process may be restarted after each calculation output time
using the \c restartOnOutput option or restarted periodically using the \c
periodicRestart option and setting \c restartPeriod to the required
averaging period.
Example of function object specification:
\verbatim
fieldAverage1
{
type fieldAverage;
functionObjectLibs ("libfieldFunctionObjects.so");
...
restartOnRestart false;
restartOnOutput false;
periodicRestart false;
restartPeriod 0.002;

mean on;
prime2Mean on;

window 10.0;
windowName w1;
}
p
{

prime2Mean on;
base time;
}
);
}

This default number of processors may be overridden by the new "-np"
option to runParallel which must be specified before the application
name e.g.:
runParallel -np 4 pisoFoam
which may be optionally overridden by version-specific rules.
For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory. If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.
