hi. How are species ordered in fluid phase? from 0 through 1,2,3 and so on?? Someone asked about it before and answer was like above but... when im trying to do a mass transfer from phase and from species (standard example from tutorials) Fluent calculates something even if I give an non existing species number. I mean i have a fluid with 2 species so its orders should be 0 and 1. isn`t it? I put 11 and 12 (small experiment just to check) and Fluent calculates something. Why?? Shouldn`t be there an error message?? It`s strange.

they start w zero and go in the order they're listed in the materials panel
