  A novel method rooted in the classical Schwarz-Christoffel transformation
from the disk is introduced, which allows for fast and accurate solution of
potential field problems in possibly inhomogeneous and multiply connected
domains: this is for sure its most outstanding feature, circumventing the
barriers that have increasingly restricted the scope of conformal mappings in
applications since the advent of computers and purely numerical methods. An
example problem, derived from a case of practical interest, is analyzed and
results are compared with those obtained from FEA.
