Cylindrical/Spherical components of E field

Hello,

Does anybody know how to use field calculator in order to obtain Cylindrical/Spherical components of E field?

There is notice in the field calculator cookbook (below) but HFSS doesn't give this information when I ask.

This calculation allows you to generate named expressions in addition to those automatically available ones in the field calculator, and save them as a user library, and reload into other designs/projects for use. For example, Cartesian components of E field are used for demonstration. If you are interested in Cylindrical/Spherical components of E field, please contact Ansoft support to obtain such libraries.

If anybody help about this, it will be appreciated.

Regards
