Cartesian coordinates transform into a cylindrical coordinates but moving the origin for 2D piezoacoustic model

I’m working on a 2D piezoacoustic model. This model has three different sections of curved PVDF piezoelectric film, arranged in line, one beside the other over the x axis. One of those sections is centered on (0,0) but the others are on each side of that centered section.
For the correctly assignation of the material polarization (radial direction), I used the coordinate transform described on the tutorial “Spherical Piezoacoustic Transducer” which defines the radial direction of the domain as the direction of polarization. That transform is centered on (0,0) and that works very well for the film section that is on (0,0), however the side ones are not well polarized, and off course, it makes the model fail.
For that, I need to know how can I create a base vector system in which I can transform the Cartesian coordinates into a cylindrical coordinates but moving the origin to, for example (5,0).
It would be very appreciated if you could give me some hints.
