Hello I attempt to solve flow of two fluids one hot and other cold through 3D channel as illustrated in pictures I was define the three domains in ANSYS meshing one for hot fluid named it oil and the second for the cold fluid named it water and a solid domain for the solid named it solid. When I open CFX I not found these domains only one default domain exist as illustrated to the left of the pictures so what the problem?

That is the default setup, i.e. join all the mesh volumes into a single domain.

Now insert a domain (name as you wish), and select the mesh volume of interest. Repeat for the other two.

You mean I did that in CFX-Pre from the option insert>Domain?

May i ask how i can make the top and bottom walls of the current channel at pictures in my first post as periodic?

Periodic boundaries are created as domain interfaces..

Insert a domain interface, select both sides, and select the type of domain interface you need.

I insert new domain interface and select the two faces but what type should i set for additional interface models to make it periodic?
