CAD/CAE integration: updating the CAD model after a FEM analysis

The improvement of the simulation process requires an integration of the design and analysis models. There are two essential tasks in the design analysis process: (i) computer-aided design (CAD) which provides the geometric description of the model and (ii) the finite element method (FEM) used for m...

Description
Summary:The improvement of the simulation process requires an integration of the design and analysis models. There are two essential tasks in the design analysis process: (i) computer-aided design (CAD) which provides the geometric description of the model and (ii) the finite element method (FEM) used for mechanical behaviour simulations. The interoperability between these two tasks reduces costs and improves product quality through the acceleration of design analysis loops. Our activity fits into this research orientation by providing a method to link the FE analysis and the CAD model. This is done by reconstructing the CAD model from the FE analysis results (deformed mesh). This paper proposes a method to update the CAD geometry from the deformed mesh. This approach allows for rebuilding the CAD model after analysis by extracting geometric information from the deformed mesh. An illustration of the developed method is discussed at the end of this paper.
