Problems solved by technology

[0002] With the development of computer-aided engineering (Computer Aided Engineering, CAE) technology, in the development process of complex products, the role of CAE analysis continues to improve, but in the traditional simulation analysis, usually with CAD (Computer Aided Design, computer-aided Design) geometry as the center, engineering data is directly attached to the geometry, according to the traditional design process, when the CAD geometric model changes, the follow-up simulation design department needs a lot of manual repetitive work to perform the simulation of the new design scheme, especially involving When it comes to the multidisciplinary simulation design of complex products, since multidisciplinary issues involve cross-departmental cooperation, a variety of simulation software is used, and each change will consume a lot of manpower and is prone to errors, resulting in a longer project cycle

Abstract

The invention relates to a computer analogue simulation analysis system and method. The method includes the steps: extracting predetermined parameterization information of an uploaded geometric model;updating the size of the geometric model according to the extracted parameterization information; selecting a portion needing grid division in the geometric model or the whole geometric model, dividing the grids and displaying a grid dividing result; performing simulation solution calculation, and outputting a simulation solution calculation result into a visible result. According to the method,the steps in CAE (computer aided engineering) analysis such as rapid modeling of CAD (computer aided design), automatic grid generation in pre-processing of CAE and setting of boundary conditions arefixed, multidisciplinary tools are integrated into the same environment, so that system designers can independently, rapidly and conveniently analyze structural modes, strength and the like, a plurality of schemes are compared, and an optimal scheme is selected, so that overall design efficiency and design level are improved.
