System and Method for analyzing Flow field and Flow Noise automatically

摘要

An automatic flow and flow noise interpretation method and a system thereof are provided to save cost and time and to make anyone easily use, compared to a method using CFD interpretation for an existing design method dependent on a designer's experience, thereby increasing marketability and utility. In a 3D data modeling step, attribute values are given according to pre-defined rules for each lattice of 3D shape data. When CAD data written by the modeling step is read from a CFD program, from a conversion information DB where border condition values and size values of the lattices per attribute value are stored, the size values and the border condition values are read to be set automatically. A flow pressure change value is calculated by execution of the CFD program. The calculated results are outputted in graph and displayed.
