Material improvisation

Please login with a confirmed email address before reporting spam

Hello
I was curious to building my own materials. Comsol allows prescribing user defined material properties, but I want to do something different. Suppose, I want to solve for flow only (spf), and my working fluid contains 99% or air and 1% Carbon di oxide. How can I do that? How can I build a material composition based or mole/mass fraction?
