Transform stress in comsol

[FEAppp]

The stress in the global coordinate is denoted as solid.sz, solid.sx and etc.

I defined a coordinate system (sys2) in comsol. How to transform the stress in the global coordinate in the sys2?

I cannot use sys2 in the solid mechanics and choose sys2 in the linear elastic material because my material is anisotropic.

So I am trying to transform it in the result plot. I found a function which is sys.T

But I don't know how it works. Does anyone have some ideas?

Thanks!

Is sys2 a cylindrical coordinate system ? Comsol has some limitations and you may have to use workarounds like this one:
