3D magnetic field analysis of permanent magnet type of MRI using preconditioned MRTR method Available to Purchase

The paper examines the convergence characteristics of the “minimized residual method based on the MRTR (three‐term recurrence formula of CG‐type) method” for solving large linear simultaneous equations.

The paper uses an example of magnetic field analysis of permanent magnet type of MRI taking account of the minor loop and eddy current.

It is shown that the preconditioned MRTR method can get a stable and quick convergence for such a relatively ill‐conditioned problem.

Illustrates that the convergence of the Incomplete Cholesky Conjugate Gradient method is one of the important issues in the practical 3D magnetic field analysis.
