ANALYSIS SIMULATION SYSTEM, ANALYSIS SIMULATION PROGRAM, AND ANALYSIS SIMULATION METHOD OF UNSTEADY FIELD

摘要

PPROBLEM TO BE SOLVED: To provide an analysis simulation system, analysis simulation program and analysis simulation method of an unsteady field capable of easily and precisely performing the simulation of the unsteady field involved in movement of an object, and significantly reducing the analysis time and analysis cost required for simulation analysis. PSOLUTION: The moving route of a mobile body in a predetermined time is set, the predetermined time is divided into a plurality of analysis times, and a mesh is set for an analysis object in the mobile body based on the moving route of the mobile body in each of the plurality of analysis times. Input of an initial condition of analysis is accepted, a boundary condition is set based on the initial condition, and the behavior of the analysis object in the first analysis time is analyzed. The calculation result output of the analysis processing is set as the boundary condition of behavior analysis of the analysis object in the next analysis time. PCOPYRIGHT: (C)2005,JPO&NCIPI
