Evaluating the partial inductance routines in the LTU-PEEC solver

Abstract [en]

The accuracy of partial inductance calculations is a strong determining factor in PEEC simulations. Errors in partial inductance routines lead to non-physical solutions. The sign of partial inductances depends on the assumed current directions in the conductor segments. The current flow in the structure under analysis is represented by the connectivity matrix (Cm). The signs of the entries in the Cm matrix can be chosen such that the final results from the PEEC simulations are independent of the initial current assumptions. This approach has been tested on a simple geometry. The numerical integration routines have been looked and it was seen that the existing numerical integration routines are only good for flat surfaces. In fact, the errors in the self terms approach 100% for structures with some thickness.
