METHOD FOR FLUID FLOW SIMULATION

摘要

PURPOSE: A fluid flow simulation method is provided to shorten a calculation amount and calculation time of a fluid flow simulation. CONSTITUTION: A calculation time interval is divided into at least one frame(S2). Each frame is divided into sub frames(S3). A fluid flow is calculated from the frame based on a linear term of a flow equation about fluid speed(S4). Fluid flows of sub frames are successively produced based on a non-linear term of the flow equation about the fluid speed(S5).
