The article discusses a method called structure parametric design for creating Finite Element Analysis (FEA) models more easily. By adjusting geometric parameters, the FEA model can be quickly modified and analyzed automatically. This method is efficient for analyzing similar products and can save time in the product design process. The researchers used ANSYS Parametric Design Language to create a practical FEA model and successfully analyzed stress in a structure, showing the method's effectiveness in FEA.
