Research and Development of Modeling-Analysis Integration System Based on Feature Association

With respect to the low efficiency caused by repeated user interactions during iterative design processes on CAD and CAE platforms, a novel integration method is proposed to merge modeling and analysis functions into one framework.Based on modeling and analysis history, the associated-action reconstruction mechanism (AARM) is proposed by using adaptive mesh grid quality control and boundary condition revision strategy.All the modules, either geometric modeling or property analysis, are operating in unified feature structures which lead to an integral synchronous design performance.For ensuring the AARM between analysis and modeling processes response in time, the FMBEM algorithm and parallel GPU acceleration strategy are introduced.In the last, aprototype system with this synchronous design method is presented, and the effectiveness of this method is verified with an example.
