Problem with Steady state AC thermal coupled with thermal transient (3D)

Hello to everyone, I am trying to perform a very easy simulation: a copper bar with fixed current, wich is the value of joule losses? Wich is the distribution of the temperature after 10 s?

To do that I set a "Steady state AC Magnetic coupled with Transient Thermal", I created a circuit (here below) with just a solid conductor, a current generator and the ground.

 I associated the solid conductors terminals to the two small surfaces. I set the lateral regions like this: Normal magnetic Field (tangential ELECTRIC filed).

 

After I solve the scenario, the check Physics is ok but I get this error:

Any clue of the reason? Thank you

    Hi Gianluca,

    I will check what is the meaning of the code error and get back to you.

    You do not have to create a boundary condition on the lateral surfaces. Create an infinite box around it. That will take care of the boundary conditions.

    Are you getting the same error with the infinite box defined?

    Thank you,

    Lavanya
