摘要： A calculation method for physical value is provided. The method may be performed by a computer having a CPU and a memory device, for calculating physical values in a numerical analysis method for numerically analyzing a physical phenomenon. The method may comprise a physical value calculation step of calculating physical values in an analysis domain divided into a plurality of cells. In the physical value calculation step, the CPU calculates the physical values by using: a discretized governing equation that uses only values not requiring coordinates (Vertex) of vertices of the cells 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 cells and characteristic values of boundary surface indicating characteristics of boundary surfaces of adjacent ones of the cells are provided. The volumes of the cells and the characteristic values of boundary surface may be the values not requiring coordinates (Vertex) of vertices of the cells and connectivity information (Connectivity) of the vertices. The values not requiring coordinates (Vertex) of vertices of the cells and connectivity information (Connectivity) of the vertices may be values that are defined without using coordinates (Vertex) of vertices of the cells and connectivity information (Connectivity) of the vertices. The discretized governing equation and the calculation data model may be stored in the memory device.
