Control the natural frequency while considering the MAC value. Utilize parallelization to handle large-scale models in a short time.
By changing the shape, we improve the natural frequency and resonance frequency. Additionally, we have added conditions to allow for die-cutting in accordance with manufacturing requirements. In recent years, the performance of PCs has increased, and the scale of models required for finite element analysis has also grown larger. In such cases, significant time savings can be achieved by utilizing parallelization. This time, we performed shape optimization on a large-scale model with over one million nodes using parallelization. 【Analysis Model】 ■ Elements: Tetrahedral second-order elements ■ Number of elements: 653,931 ■ Number of nodes: 1,026,428 <Related Keywords> - Rib shape - Matching considering MAC values - Controlling eigenvalues *For more details, please refer to the PDF document or feel free to contact us.
