Class
Foam::clouds::dynamicParcel
Description
Basic cloud with spherical, variable density, particles, grouped into
parcels.
This cloud's modelling is the same as for dynamicParticle, except that an
additional number field is used to represent multiple physical particles
per Lagrangian parcel. This adds flexibility with regards to managing the
expense of simulating large numbers of physical particles, and also
provides the ability to specify the number, size (distribution) and volume
or mass flow rate of particles at an injection.
