PatchInjection: Initial Particle Position

Hi,

I wanted to use patchInjection model for my particle simulation. I want to know what is the initial starting position of parcels/injectors at the specified patch. It is uniformly distributed or parabolic or base on some random function.

From the file PatchInjection.H:

Code:

 //- List of cell labels corresponding to injector positions

        labelList cellOwners_;

I understood initial position of parcels/injectors is defined by cellOwners_

In file PatchInjection.C:

Code:

cellOwners_ = patch.faceCells();

This tells me position of injectors is taken at face cells.

What I am unable to interpret is if number of parcel/injectors specified are less than no. of cell centers than how the parcels/injectors position is decided on given patch?

base patch injection - number of parcel/injectors relation to number of cell center
