I am having a little doubt concerning the use of boxes in the Lagrangian Module.
In fact, I would like to modelize the expansion of a virus, and this virus would be in diferent carriers (fish, plankton,...). There would be three carriers: one by plankton, one by fishes, and the other one would represent the virus as a particle itself.
For that, I know the place of the origin of the emission, I would like to make a origin box with the dimensions 30*30*15 metres.The three type of boxes would have this same box origin, and then they will have a diferent evolution because of their difference in concentration ect...
My doubt is about how to do that?!!!

In fact, I have begun doing my lagrangian module. will the 3 boxes have the same begin origin? (I imagine yes), and then I have to write box number : 3, and make 3 properties bloks?
This is what I have wrote for the moment:
OUTPUT_TIME : 0 3600
OUTPUT_CONC : 2
DT_OUTPUT_TIME : 3600

Another questions:
- how do I make the PARTIC_BOX (the origin box? with mohid gis...?)
- what is the function of the BOX_FLUXES keyword?
- what is the name keyword to put for a virus? particulate contaminant?
- Is there a keyword to ,ak a particle duplicate (not in volume, duplication like baterias...)?
Thank you in advance for your answers, have a nice day!
