Improvement of convergence characteristic of ICCG method for the A-φ method using edge elements
Year: 1996
Type: article
Abstract: The effect of the scalar potential /spl phi/ in the A-/spl phi/ 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 /spl phi/ and neglecting /spl phi/ to compare the convergence characteristics. It is illustrated that the CPU time using /spl phi/ is less than 1/2 of that neglecting /spl phi/, and there are some models in which the use of /spl phi/ enables us to obtain convergent solutions.
