Finite Elements for Electrical Engineers
But U may be used to compute a new set of reluctivities, which can in turn be
employed to calculate another approximation to U. The process can be begun by
assuming initial (zero-field) reluctivity values everywhere, and can be terminated
...

According to a theoretical study by Poussin and Lion ( 8 ) the reason for
convergence troubles is the large difference between the reluctivities of the air
and iron regions. The application of the additive acceleration of convergence
consists of: 1.

These reluctivities are calculated from the magnetization characteristic and a
knowledge of the local magnetic induction. When the vector potentials at the r-th
iteration are obtained, the reluctivities are recalculated and the procedure is ...
had to be subdivided in two to four parts to ascertain that the relaxation
procedures converge well. The calculation of the reluctivity in the saturated
region from an improper fit can lead to large values of reluctivities that hamper
convergence, ...

As an adjustment, the vector potentials of all grid points of a gridline KM are
reduced by A = (i) [A (1, K) - A (Jmax, K)] (3.19) Underrelaxation of Reluctivities
The reluctivities can now be recalculated. Using experience with similar
programs ...

RELUCTIVITY AND BOUNDARY CONDITIONS IN FINITE DIFFERENCE FORM
In the present scheme the reluctivities are defined on the gridlines in the center
between mesh points as shown in Figure 2. 8. F.C. Trutt, E.A. Erdelyi and R.F. ...

Calculation of Reluctivities If nonlinear field problems are considered, the
reluctivities of all meshes are updated after every two or four sweeps using the
procedure by Trutt and others [9], where under-relaxation is applied to the
calculation of ...

Overrelaxation of the vector potentials with an overrelaxation factor of 1.3 and the
underrelaxation of the reluctivities with an underrelaxation factor of 0.1 appear to
yield faster convergence. Besides the use of these factors, a block relaxation ...
