摘要

The present invention provides a 3D simulation model that can be implemented in an MBD program. A computer divides an analysis area into a plurality of divided areas, and volumes of each divided area and divided area characteristic quantities indicating characteristics of adjacent divided areas are coordinates of vertices of divided areas and connection of the vertices. A data model for calculation in divided areas having information as an unnecessary amount is generated, and a plurality of divided areas are assembled to generate a required number of aggregation areas, and an aggregation area adjacent to the volume of each aggregation area Generate a data model for calculation in the set area having the coordinate of the vertex of the set area as the set area characteristic quantity indicating the characteristics of each other and the amount not requiring the connection information of the apex, and the physical property value in the analysis area; Based on the calculation data model in the collective area, a conductance representing the characteristic of movement of physical quantities between the collective areas and out of the analysis area, and a characteristic representing the characteristic of accumulation of the physical quantity of the collective area To calculate and Shitansu.
