CALCULATION METHOD FOR PHYSICAL VALUE, NUMERICAL ANALYSIS METHOD, CALCULATION PROGRAM FOR PHYSICAL VALUE, NUMERICAL ANALYSIS PROGRAM, CALCULATION DEVICE FOR PHYSICAL VALUE, AND NUMERICAL ANALYSIS DEVICE

A calculation method for physical value for calculating physical values in a numerical analysis method for numerically analyzing a physical phenomenon, comprises a physical value calculation step of calculating physical values in an analysis domain divided into a plurality of divided domains, wherein in the physical value calculation step, the physical values are calculated by using: a discretized governing equation that uses values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices and that is derived on the basis of a weighted residual method; and a calculation data model in which volumes of the divided domains and characteristic values of boundary surface indicating characteristics of boundary surfaces of adjacent ones of the divided domains are provided as the values not requiring coordinates (Vertex) of vertices of the divided domains and connectivity information (Connectivity) of the vertices.
