Domain-Integrated Field Equations Approach to Static Magnetic Field Computation—Application to Some Two-Dimensional Configurations

The recently developed domain-integrated field equations approach to static magnetic field computation is applied to some two-dimensional configurations, viz. a model rotor/stator slot configuration and a model magnetic recording head configuration. Consistently linear edge expansion functions are used for the magnetic field strength, together with consistently linear face expansion functions for the magnetic flux density, both on a triangular mesh. The method handles large contrasts in material properties on a coarse mesh, with excellent global error properties, in acceptable computation times.
