Is it possible to specify permittivity and permeability values of an anisotropic material directly in cylindrical coordinates i.e εr,εθ and εz in the RF solver or it needs to be converted to cartesian coordinate system first?

I have same problem. I try to define a cilidrical coordinate and use de properties in function of sys.r that is the r in the cylindrical properties.
But I have two cilidres no parallel and I don`t know how do it.

Please, Somebody know how to do it or where can i looking for information about this.
