FLUID MOTION ANALYZING DEVICE AND METHOD, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a fluid motion analyzing device capable of stably and easily analyzing the fluid motion even when an hardly analyzable item instable in analysis is included in a non-steady advection diffusion equation under a specific condition. SOLUTION: This fluid motion analyzing device 1 is provided with an integral data calculating part 151 for integrating and calculating an advection term included in the non-steady advection diffusion equation. Further, a non-advection term data calculating part 16 is provided to calculate the non-advection terms as the terms excluding the advection term, included in the non-steady advection diffusion equation by a finite difference method.
