About this paper
Andrea Serani, Matteo Diez
Andrea Serani and Matteo Diez from the National Research Council – Institute of Marine Engineering provide a comprehensive scoping review and classification of design-space dimensionality reduction methods specifically for external shape optimization problems. The review details various linear and nonlinear techniques, highlighting a cubic trend in related publications and offering statistical insights into current research focuses.
Key insights
- The field of design-space dimensionality reduction for shape optimization is experiencing a cubic growth trend in publications, reflecting increasing research interest.
- Direct dimensionality reduction methods, particularly linear techniques such as PCA/KLE/POD, are predominantly employed, accounting for 80% of direct approaches.
- Advanced methods like Parametric Model Embedding (PME) are crucial for practical applications by explicitly linking reduced dimensions back to original design variables, addressing the pre-image problem.
