Geometry Modeling for Patterned and Repetitive Configurations: a Noval Approach for Designing Biomedical Stents

Over the years, the use of computational engineering applications such as computer-aided design (CAD), computational fluid dynamics (CFD), and computational structural mechanics (CSM) has grown rapidly in the aerospace, automotive, electronics, biomedical, and many other industries. All computer-based design tasks commence with the use of CAD systems to create detailed geometrical models. These models serve as a basis for diverse analysis tools, such as CFD and CSM, which would require another process called mesh generation to generate discrete spatial points for CFD and CSM tools to use in performing analyses. The accuracy of the analysis depends on the geometrical fidelity, the quality of the meshes, and the accuracy of the mathematical models. Any of these steps can often become a hurdle that requires tedious user interactions and parameter modifications. This work is an effort to address this issue, primarily by designing, modeling, and meshing complex patterned and repetitive geometries, such as springs or cardiac stents, using parametric geometry design and template mesh generation approaches.
