Mapped infinite elements for the solution of open electric and magnetic field problems

A Coupling Between the Facet Finite Element and Reluctance Network Methods in 3-D

“…Even though a weak field is computed close to those regions, this behavior cannot be desirable and can be minimized by increasing the X dimensions of the air regions, possibly unifying the domains. A more interesting and definitive solution would be to apply the "infinite" finite elements theory [41] in the X direction on those surfaces.…”
