A comparison of different testing procedures for subdomain moment‐method formulations for arbitrarily shaped bodies, including attached wires, is presented here. It is shown that an accurate evaluation of the impedance matrix elements leads to important benefits over the conventional procedures. Otherwise, the use of an adaptively generated mesh—more refined nearby the sources—is shown to reduce the total number of unknowns, and therefore, the computational cost for a fixed problem. © 2000 John Wiley & Sons, Inc.
