Hi everyone, i have a general question.

If I'm not wrong, for a 2D axisymmetric thermal analysis, the software works with the X-axis as axis of rotatio, thus the geometry must be set up in order to have the X-axis as rotation and the object has to be in the +Y region. Now, it seems, instead, that for the mechanical study, the rotational axis must be the Y-axis. I'm performing a coupled thermo-mechanical analysis, how do I figure this problem out? I mean, as I have to take the temperature map from the thermal model to apply it on my mechanical analysis, i struggle to understand how todo it, as the mechanical solver wants the model to spin around the Y-axis

Thanks for the help!

I am not sure where you are seeing X being axis of rotation for 2D axisymmetric analysis. In Mechanical, for 2D axisymmetry X is radial and Y is axial or axis of rotation. This is true whether it is thermal (e.g.plane55), structural or coupled thermal-structural (e.g. plane223 shown below).
