cloudInfo

This is a functionObject for OpenFOAM.

used to get cloud information, e.g., number of parcels, total mass, penetration, spray angle. It can be used in run time or as postprocessing, see setting below

Run time setting

In system/controlDict, add the following cloudInfo1 function, revise the type, clouds, penetration, position, and direction according to the constant/XXXCloudProperties.

functions
{
    cloudInfo1
    {
        libs            ("liblagrangianCloudInfoFunctionObjects.so");
        type            basicSprayCloudInfo;//basicReactingMultiphaseCloudInfo;
        //basicReactingMultiphaseCloudInfo;//for reactingParcelFoam and coalChemistryFoam
        //basicSprayCloudInfo;//for sprayFoam
        //basicKinematicMPPICCloudInfo;//
        //basicThermoCloudInfo;// for I dont know which Foam, you can see the name in createClouds.H
        //basicKinematicCloudInfo;//
        //basicKinematicCollidingCloudInfo;//
        //basicReactingCloudInfo;//
        clouds          sprayCloud;//(reactingCloud1); // cloud name, i.e., the folder name in 0/lagrangian

        enabled         true;
        writeControl    timeStep;
        writeInterval   1;

        penetration     0.95;    // fraction of the total mass, in [0, 1]
        position        (0 0 0); // initial position
        direction       (1 0 0); // initial spray direction
    }
}

Postprocessing

Create a file, e.g., cloudInfo, in system/ folder, and then run sprayFoam -postProcess -func cloudInfo.
