| 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. | |
