Hi all,
I just wanted to know how to model multicomponent flow in ansys cfx. I've been running a simulation consisting of H2, N2, O2 & H2O as ideal gases, but somehow in cfx solve, it runs as a multiphase simulation. Is there a specific setting to model multicomponent flow rather than multiphase flow? Also, why is it considering this above gas mixture as multiphase flow? Any help will be gladly appreciated.

chk this:

Also ensure that you have set the interaction between phases to none.
