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;

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.
This function object calculates mole-fraction fields from the mass-fraction
fields of the psi/rhoReactionThermo and caches them for output and further
post-processing.
The names of the mole-fraction fields are obtained from the corresponding
mass-fraction fields prepended by "X_"
Example of function object specification:
moleFractions
{
type psiReactionThermoMoleFractions;
}
or
moleFractions
{
type rhoReactionThermoMoleFractions;
}
depending on the thermodynamics package used in the solver.
