Parametric modeling is a technique where models are created and analyzed using parameters or variables instead of fixed values. This approach allows for the easy generation and evaluation of new models simply by adjusting these design parameters. These parameters can represent not only geometric dimensions but also properties such as temperature and material characteristics.
In parameterized geometric modeling systems, the design parameters are confined to the geometric model itself. However, these geometric models cannot be directly used for analysis or calculations. They must first be converted into finite element models, which are compatible with analysis and optimization software.
To effectively use design parameters from the geometric model as variables for shape optimization, it is crucial to extend these parameters to the finite element model. This extension enables the finite element model to be parameterized according to changes in the design variables, allowing for more efficient analysis and optimization.
