In their paper, the authors compare three formulations for the numerical computation of the magnetostatic field. One of these formulations involves the reduced scalar potential for which the following boundary conditions are necessary at the interface between regions of different material:

A formulation based on scalar potentials for the numerical solution of three-dimensional nonlinear static electromagnetic field problems is presented. The resulting equations are solved using finite elements, based on a Galerkin procedure. A general-purpose package called TOSCA has been developed, implemented and tested. Results are presented for three cases and compared with measured values.

Key developments in computational electromagnetics are proposed. Historical highlights are summarized concentrating on the two main approaches of differential and integral methods. This is seen as timely as a retrospective analysis is needed to minimize duplication and to help settle questions of attribution.
