Madison Dittner
M.Sc. Student (Summer 2018 – Spring 2020)
Current: The United States Patent and Trademark Office
Madison’s research was focused on developing a numerical platform for geometry optimization. Madison developed a Genetic Algorithm that employs two commercial software packages (ANSYS and Solidworks). The GA model assigns values to the parameters that are used to characterize the geometry of interest. Solidworks makes the geometry and forwards it to ANSYS. Fluent module of ANSYS develops a CFD simulation for the new geometry and forwards results of interest back to the GA model. GA uses the simulation results to modify the geometric parameters. This continues until the optimal geometry is research. Madison uses TN Tech’s high-performance computing cluster to conduct CFD simulations.
