Air properties
 
Hello,
I read from previous posts that if I'm using AIR AT 25, density of air doesn't change with temperature. If it is true, my question is how to define it in material library.
Thank you for advice.

Have a look in the tutorials for examples. Any compressible flow example would show how to do it.

I was looking into a lot of tutorials but I haven't found anything yet. But I tried to create my own air with defining the air density according to temperature but I have a big scale of temperature. Range from 20 - 800 degrees. Should I do it manually with step 1C or could I do it some other way. And what about other properties of air when I'm simulating fire. Do I need them? Thank you for your help.

Use "Air Ideal Gas". Lots of the tutorials use this.
