If I'm not wrong, for a 2D axisymmetric thermal analysis, the software works with the X-axis as axis of rotatio,

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).
