摘要：An object of the present invention is to analyze a fluid flow with high accuracy and a simple configuration while suppressing a calculation load. A calculation calculation model, a calculation condition, and an initial value are acquired, a numerical calculation
target model is defined by dividing a region by a plurality of elements (S100), processing relating to boundary movement is executed (S102), An intersection (boundary point) with a calculation point of the calculation grid is extracted (S104), a unit vector in the tangential direction on the boundary surface is calculated (S106), and a velocity gradient in one direction at the boundary point is calculated (S108). The velocity gradient in the remaining direction at the boundary point is calculated (S110), the velocity field and the pressure field of the fluid are calculated (S112), and the calculation result is output
(S116). As a result, the velocity gradient can be obtained with high accuracy with less calculation point information than in the extrapolation method, and the fluid flow can be analyzed with high accuracy with a simple configuration while suppressing the calculation load. [Selection] Figure 6
