Fluidized bed in Gambit

Hi all

How to draw fluidized bed with the distributor consisted of a perforated plate of open area ratio 1.2% in GAMBIT ?

do you have a picture of this distributor?

No i don't have a picture of distributor .this geometry is in a paper and i want reproduce results of that paper .
in paper only that picture shown.And has written about the distributor :
The distributor consisted of a perforated plate of open area
ratio 1.2%.

i don't know how to draw this geometry in gambit

Then draw a plate, which is perforated from N holes with diameter D
The ration between cumulated hole-area (0.25.N.pi.D^2) and inital plate is given (1.2%).
Ther is also the possibilty to work with porous media or something like that, but I neved used it
