Class-dependency diagram, showing how a CloudFunctionObject (here: ParticleTrap, which is merely an example) is added to the runtime selection table and thus made visible to the rest of OpenFOAM. makeBasicKinematicParcelSubmodels.C is an example: one such C-file exists for every cloud existing in OpenFOAM.

makeParcelCloudFunctionObjects.H holds a list of all CloudFunctionObjects (hard-coded), and thus must be changed if one wishes to add one’s own custom CloudFunctionObject. CloudFunctionObject.H holds macros which manage the runtime selection table in a templated manner. For a custom CloudFunctionObject, these should be called, but not altered.
