It's not mandatory, but it improves the solution close to the symmetry
axis. If you are interested, this change of variables is described in
@article{henrotte.GeoTrans,
author = "F. Henrotte and B. Meys and H. Hedia and P. Dular
and W. Legros",
title = "Finite element modelling with transformation
techniques",
journal = "IEEE Transactions on Magnetics",
volume = 35,
number = 3,
pages = "1434--1437",
year = "1999",
}
Best,
Christophe
