抄録

The effect of the scalar potential φ in the A-φ method on the convergence characteristic of the incomplete Cholesky conjugate gradient (ICCG) method using the edge element is investigated. Several 3-D eddy current models are analyzed both by taking into account φ and neglecting φ to compare the convergence characteristics. It is illustrated that the CPU time using φ is less than ½ of that neglecting φ, and there are some models in which the use of φ enables us to obtain convergent solutions
