Default how to simulate a condensation problem

siden is on a distinguished road

I have to modelize the condensation in the output of a heater.

so I have smoke elements (CO2, N2, O2, H2O). I can make condensation with H2O but not when others coponents are presents.

if i use a multi phase model, the CFX-pre is not happy.

I found an example in the tutorial of ansys, the one with steam jet condensation but it's too complicated.

someone have an idea about that?

Multiphase models are complicated.

If you can simplify your condensation down to something you can easily apply using source terms then go for it, but otherwise you will be forced to use some pretty complex models to get this to work.
