Title:
ANALYSIS METHOD, ANALYZER, AND ANALYSIS PROGRAM
Document Type and Number:
Japanese Patent JP2023021712
Kind Code:
A
Abstract:
To reduce the calculation time of an electromagnetic field in the FDTD method and reduce the amount of usage of a memory.SOLUTION: An analysis method of an embodiment is an analysis method for performing electromagnetic field analysis by using the finite-difference time-domain method (FDTD method). The analysis method of the embodiment includes: setting a plurality of voxels in an analysis area; setting at least one of the plurality of voxels as a release voxel based on a model of the analysis area; and repeatedly executing updating a time step and electromagnetic field component calculation processing targeted for each of the plurality of voxels. The calculation processing includes calculation of electric field components targeted for the plurality of voxels and application of an absorption boundary condition to the electric field components. In the calculation processing, calculation of the electric field component targeted for at least one release voxel is omitted.SELECTED DRAWING: Figure 7
