The averaging model performs the Lagrangian->Eulerian mapping of data (e.g. particle velocities). In the “cfdemParticle cloud” this averaging model is used to calculate the average particle velocity inside a CFD cell. The “dilute” model is supposed to be applied to cases where the granular regime is rather dilute. The particle velocity inside a CFD cell is evaluated from a single particle in a cell (no averaging).
This model is computationally efficient, but should only be used when only one particle is inside one CFD cell.
