AN AUTOMATIC TECHNIQUE FOR CAE ANALYSIS WITH A 3D-CAD MODEL

摘要

A CAE (computer-aided engineering) analysis system, consisting of a 3D-CAD (three-dimensional computer -aided design) modeler, a pre-processor, an analysis solver, and a postprocessor, was developed. This system uses automated procedures for solid modeling, definition of analysis models (i.e., defining boundary conditions and material properties, traditionally done manually), mesh generation, numerical simulation, and visualization of results. The CAE analysis system has two key features: it can greatly reduce the analysis time, and it uses a 3D-CAD model as the geometric model for numerical analysis. It was found that the developed automatic system reduces the analysis time by 50% compared with that for manual operation.
