Abstract
An improved version of the variational method has been developed for spreading resistance calculations, based on a different source function from one used previously. This new version is capable of great accuracy, yielding results which for most practical purposes can be regarded as indistinguishable from those obtained from the exact method using the mixed boundary value approach. At the same time, it retains the main advantage, namely, speed of computation, of the variational method. Thus, in its present form, the variational method can be used in place of the exact method for accurate determination of both the correction factors and the source current density, especially where speed of computation is an important consideration. © 1986.
