摘要

PROBLEM TO BE SOLVED: To provide a boundary condition setting program or the like capable of setting a boundary condition capable of calculating a distribution of a physical quantity with high accuracy and obtaining a more realistic calculation result while suppressing the amount of memory. SOLUTION: This is a boundary condition setting program for setting the condition of the area boundary of the target area for analyzing the distribution of physical quantities, and the discrete value on the outermost boundary surface of the outermost boundary in the virtual outer boundary area is set to the quasi-outermost boundary surface. Derivation of the outermost boundary propagation matrix that linearly transforms from the discrete values on the quasi-outermost boundary surface of The innermost boundary propagation matrix, which linearly transforms from the domain boundary propagation value, is derived based on the outermost boundary propagation matrix, and the innermost boundary propagation matrix, the domain boundary discrete value, and (A) discrete on the innermost boundary surface. The computer is made to derive a connection matrix connecting the domain boundary of the target region and the virtual circumscribing region from the relational expression with at least one of the value and (B) the discrete value between the region boundary and the innermost boundary surface.
