[Example] Efficiency improvement of repetitive calculations using the super element function.

basic information

**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Industry: Mechanical Components The super-element feature of Simcenter Nastran reduces computational load by dividing large models for analysis or by simplifying parts of the model (external super-elements), thereby reducing the size of the analysis model and shortening computation time when changes are made to other parts. In this case, we verified the analysis accuracy and evaluated the reduction in computation time by simplifying the unchanged boss section as an external super-element and analyzing it in conjunction with the mesh model of the blade section during the eigenvalue design of the fan blades. This method saves computation time in cases where there are many repeated calculations, such as performance evaluations during the design phase or countermeasure considerations at the component level, and the more unchanged parts there are, the more significant the benefits. Additionally, by creating super-element models of in-house components and providing them to other companies, the shape can be treated as a black box, which can also be utilized for information security. □ For other features and details, please refer to the catalog.
