MAT9 orientation with CORD2S?

[titouantlse]

Hello,

I would like to orientate a MAT9 material on a paraboloid shape with a CORD2S (spherical coordonate system).
I reached to do that. I can see how is orientate the material Z direction but I do not know how to check and MODIFY X and Y direction of the material.
In fact, I would like to be able to modify X and Y material orientation with several CORD2S.

Thanks for your help
