Computer methods for electrical and magnetic devices designed by field analysis

This paper reports the work done by the authors in developing computer methods for electromagnetic field analysis. The work which began at two-dimensional saturated field calculation with currents and permanent magnets, has been extended to three-dimensional scalar fields. The use of boundary integral methods allows a drastic saving in user and computer time for a class of problems. Currently an analysis of magnetohydrodynamics problems by finite elements method is under development.
