Abstract:
1. A computer-readable recording medium that stores therein a computer program that causes a computer to execute a mutual immittance calculation, said calculation comprising: inputting data of a model of an electric circuit apparatus, being a target for analysis of the electromagnetic-field strength and being divided into a plurality of patches having points at corners and edges connecting pairs of points; discriminating a main portion from an additional portion in the patches; creating a table representing correspondence between the edges, points and patches; setting a mode, where the mode corresponds to a linear dimension of the electric circuit apparatus, for the main portion and the additional portion; calculating the mutual immittance for combinations of patches corresponding to the main portion and calculating the mutual immittance for combinations of patches corresponding to the additional portion using the table; and storing a result of calculating the mutual immittance corresponding to the main portion, wherein when the mutual immittance calculation is made to the model in which only the additional portion has been changed for a second time onward, the mutual immittance corresponding to the changed additional portion is recalculated using the stored calculation result, and when the mutual immittance calculation is made in a boundary portion between the main portion and the additional portion is designated as a combination between patches corresponding to the additional portion.
