Abstract

A new integral code employing edge elements rather than nodal elements has overcome the difficulties associated with earlier integral codes. By using field integrals (potential differences) as solution variables, the number of unknowns is reduced to one less than the number of nodes. Two examples, a hollow iron sphere and the dipole magnet of the Advanced Photon Source injector synchrotron, show the capability of the code. The CPU time requirements are comparable to those of three-dimensional finite-element codes. Experiments show that in practice it can realize much of the potential CPU time savings that parallel processing makes possible.<>
