This function calculates integral (integer moments) or mean properties
(mean, variance, standard deviation) of a size distribution computed with
multiphaseEulerFoam. It has to be run with multiphaseEulerFoam, either
at run-time or with -postProcess. It will not work with the postProcess
utility.
The following function object specification for example returns the first
moment of the volume-based number density function which is equivalent to
the phase fraction of the particulate phase:
moments
{
type moments;
libs ("libmultiphaseEulerFoamFunctionObjects.so");
executeControl timeStep;
writeControl writeTime;
populationBalance bubbles;
momentType integerMoment;
coordinateType volume;
order 1;
}
The same can be achieved using a packaged function:
#includeFunc moments
(
populationBalance=bubbles,
momentType=integerMoment,
coordinateType=volume,
order=1,
funcName=moments
)
Or on the command line:
multiphaseEulerFoam -postProcess -func "
moments
(
populationBalance=bubbles,
momentType=integerMoment,
coordinateType=volume,
order=1,
funcName=moments
)"

OpenFOAM Configuration
The main OpenFOAM settings are located in the parent etc/ directory. The bash and csh shells are supported and to configure OpenFOAM source etc/bashrc or etc/cshrc respectively which source the following files in the config.sh or config.csh respectively:
settings: core settingsaliases: aliases for interactive shellsunset: sourced to clear as many OpenFOAM environment settings as possiblempi: MPI communications library settingsensight: application settings for EnSightparaview: application settings for ParaViewscotch: application settings for compiling against scotchmetis: application settings for compiling against metis 5
The config.*/example directories contains various example configuration files for the corresponding shell:
compiler: an example of fine tuning ThirdParty compiler settingsopenmpi: an example of fine tuning openmpi settings for OpenFOAMparaview: an example of chaining to the standard config/paraview with a different ParaView_VERSIONprefs: an example of supplying alternative site-defined settings
