Resumen de Efficient treatment of infinite boundaries in electromagnetic field problems
This work discusses the use of exponentially and reciprocally decaying infinite elements and assesses their respective value for magnetostatic and eddy current problems. In particular, the need for different decaying parameters for different materials is shown to be detrimental to their application in many practical situations. A simple method, whereby a 2‐D solution is used to find the approximate boundary conditions for a closely truncated 3‐D mesh is presented and shown to give good results without the complications of infinite elements. This method is applied to a large eddy current problem.
