cylinder of two materials with mechanical thermal stress

[jacopo.greguoldo]

Hello everyone, it's my first post here, I'm pressing that I'm a user with the very first weapons.
I come to this point: I have to make a simulation of the thermo-mechanical stress of two coaxial cylinders, the internal one at a certain temperature t greater than the external one.
Could you tell me how to set the problem on ansys, since it's the first time I use it?

Thank you very much in advance

jacopo, the first thing to do when entering the forum is to make a minimum presentation.
Then, let me tell you that, being in the first weapons, you can't ask to do certain things when you don't have the knowledge of the basics of the software.
Finally, questions must be asked in a coherent and definite manner.
How are the two cylinders, are they in contact?
if you leave doubts you will get further doubts in the answers.
Hi.

Okay, I apologize for the brutality that I put the question there. I am a student of mechanical engineering of audition and I am about to finish the three-year term. in these years I learned to use autocad, inventor, solidedge and this year some ansys, but really little, we did just a couple of exercises: a reticular beam and a traction-solicited plate (it seems to recall)

the exercise I have to present now is the following (I describe it better than my first message):
There are two coaxial cylinders that "touch"
the internal one, ranging from r=0 to r=ra is aluminum to 660 degrees
the outer one, ranging from r=ra to r=rb is of steel aisi at room temperature.
I have to make a simulation of the radial and circumferential tensions present in the materials and then compare them with the analytical result that I calculated x my account.

As long as it comes to defining the geometry of the problem I believe to get there, if nothing else repeating step by step what is done for the exercise of the loaded plate, but then, to "say" to ansys of the thermal stresses, I do not know how to do, x this I turned to you here, I hope to have been more exhaustive than the previous time
