The conjugate gradient-fast multipole method (CG-FMM) is one of the powerful methods for analysis of large-scale electromagnetic problems.
It is also known that CPU time and computer memory can be reduced by CG-FMM but such computational cost of CG-FMM depends on shape and electrical properties of an analysis model.
In this paper, relation between the number of multipoles and the number of segments in each group is derived from dimension of segment arrangement in four typical wiregrid models.
Based on the relation and numerical results for these typical models, the CPU time per iteration and the computer memory are quantitatively discussed.
In addition, the number of iteration steps, which is related to condition number of impedance matrix and analysis model, is also considered by a physical point of view. |
