Hello everyone,

I am trying to model a simple membrane module with CFX. My current problem is an error when I define two gas materials. The error message said that one constraint component is required for the component fluid models. However, I can not find any positions to fill in the 'fluid models' page for the default domain.

I defined the option for heat transfer to be isothermal at 378K and defined the option for turbulence to be k-Epsilon. None for combustion and none for thermal radiation. Also, the options for two materials(C2H6O & H2O) both is transport equation. That's all what I have set.

I'm a new one in CFX. Hope for help and I would appreciate that very much.
