Document Type and Number:
Japanese Patent JP7102741
Kind Code:
B2
Abstract:
To analyze the flow of fluid with high accuracy with a simple configuration while suppressing a calculation load.SOLUTION: A calculation lattice, a calculation condition, and an initial value are acquired to define a numerical calculation object model obtained by dividing an area with a plurality of elements (S100), processing about movement of a boundary is executed (S102), an intersection point (boundary point) between the boundary and the calculation lattice is extracted (S104), and a unit vector in a tangential direction on a boundary surface is calculated (S106). Then, a velocity gradient in one direction at the boundary point is calculated (S108), a velocity gradient in a residual direction at the boundary point is calculated (S110), a velocity field of the fluid and a pressure field are calculated (S112), and the calculation result is outputted (S116). Consequently, a velocity gradient can be acquired with high accuracy with information on a calculation point smaller than in an extrapolation method, and the flow of the fluid can be analyzed with high accuracy with a simple configuration while suppressing a calculation load.SELECTED DRAWING: Figure 6
