摘要

A simulation method executed by a computer includes: dividing an analysis domain into divided domains; generating a calculation data model on the divided domains that includes the volume of each divided domain and a characteristic of the domain with respect to each adjacent domain as the quantities not requiring the vertices and connectivity; generating a requested number of aggregated domains by aggregating the divided domains; generating a calculation data model on the aggregated domains that includes the volume of each aggregated domain and a characteristic quantity of the domain with respect to each adjacent domain as the quantities not requiring the vertices and connectivity; and calculating with respect to the physical quantity, based on a physical property in the analysis domain and the calculation data model on the aggregated domains, conductance representing transfer characteristic between the aggregated domains, and capacitance representing accumulation characteristic for each aggregated domain.
