Hi,

I am using lagrangian solvers in OpenFoam. The particles form parcels and the parcels form clouds there.
I have two questions:

1) Do particles leave a parcel or do parcels leave a cloud? If not I don't get why should we define particles and parcels. If they leave, how their position for the next time step are estimated. For instance what happens if the particle position is estimated to be at a point "A" while there is no parcel/cloud there.

2) Only the particles size are defined at the input cloudProperties file in the constant folder. Shall I expect to see larger clouds in the postprocessing visualization step with paraview for larger particle sizes?

Cheers,
Emad
