FLUID TRANSITION ROUTE ACQUISITION APPARATUS, FLUID TRANSITION ROUTE ACQUISITION METHOD, AND PROGRAM

A pattern transition information on whether a structurally stable flow pattern in whole or in part of a topological two-dimensional flow structure can transition to another structurally stable flow pattern via a structurally unstable flow pattern in an intermediate state is stored, and according to the pattern transition information, transition information on a transition route from a specified structurally stable flow pattern to another structurally stable flow pattern that can be topologically adopted is acquired.
