CFX mixing pipe tee
 

I´m using CFX tp calculate the temprature profile in pipe mixing tee but i want o use to difrece materials not homogeneous. Is there some bodys to let me know how can i Make simulations between tow deffrece materials

I do not understand your question. Can you say it again please?

i want to use diffrence materail in CFX, gas and cold air but i dont know how to use it in the domain. what i should do?

Temperature is not a material property, it is a simulation variable.

Setting up material properties is described in the CFX tutorials.
