Abstract :
An equivalent current is used to remove difficulties with multiply connected regions of electromagnetic (EM) fields, and an efficient Gauss integration scheme applicable to general 3D EM field problems is outlined. The application of the integration method to singular and near singular integrals is described. Predicted 3D eddy current and field distributions are compared with available experimental and analytical results, showing good agreement. A subtriangulation scheme to evaluate singular and near singular integrals encountered in solving 3D EM field problems is also presented. Its principal advantage is that it is easy to implement
