Two domain

Hi gays, I need to design two bodies for simulated two different domain in cfx. how I can to do this?

I do not understand your question.

I need to draw two different bodies united in the same geometry design modeler, and then generate a mesh in ICEM and export to CFX, where I will have two domains as initial condition.
Remember that wanted to form oxide in the pipe wall, but how much time I have to defend my dissertation, I decided to create a domain as the oxide. but when you step geometry with two bodies to the ICEM it is not recognizing them.
So I would like to know how to keep these two bodies in ICEM to be two different domains in CFX pre?

If you draw two separate volume bodies in icem that are connected by a common surface, you just have to create then two material points (button "create body" under the geometry tab in ICEM). One material point in each volume body. Then you can mesh the two bodies and export the mesh to CFX Pre and it will recognize the two different volume regions as 2 domains with the name of the respective material point.

At least that's the way it should work...better the way I always do it and it works.

Have you looked at the meshign tutorials, including those on the ANSYS Customer page? This is basic meshing operations with ICEM.
