摘要

PROBLEM TO BE SOLVED: To provide a 3D simulation model which can be implemented in an MBD program. A computer divides an analysis region into a plurality of divided regions, and divides the volume of each divided region and a divided region characteristic amount indicating the characteristics of adjacent divided regions into the coordinates of the vertices of the divided regions and the connection of the vertices. A data model for calculation in a divided domain having an amount that does not require information is generated, and by assembling a plurality of divided domains, a required number of aggregate domains are generated, and an aggregate domain adjacent to the volume of each aggregate domain is generated. A data model for calculation in a set domain having a set domain characteristic quantity indicating the characteristics of each other as an amount that does not require the coordinates of the vertices of the set domain and the connection information of the vertices is generated, and the physical property values in the analysis domain and the physical property values in the analysis domain are generated. Based on the calculation data model in the aggregate domain, the conductance representing the characteristics of the movement of the physical quantity between the aggregate regions and outside the analysis region and the capacitance representing the characteristics of the accumulation of the physical quantity in the aggregate region are calculated.
