Voxdale used Flomerics’ EFD.Pro computational fluid dynamics (CFD) software to solve a power LED thermal management problem. The initial prototype overheated, reducing the amount of light delivered by the device and its lifetime. Thermal design typically represents the greatest challenge in LED system design; Voxdale engineers used the CFD results to redesign the housing in one day to improve airflow, eliminating overheating and improving light output and life. New generation CFD software allows engineers to focus on the fluid dynamics of the product rather than mastering the computational part. EFD.Pro uses native Pro/ENGINEER CAD data and automatically grids the flow space and manages flow parameters as object-based features to simulate design.
