Benchmark 3D Spatial Frame Model for Dynamic Substructuring and Model Order Reduction

Title (数据集标题建议): Benchmark Dataset for Dynamic Substructuring and Parametric Model Order Reduction of a Spatial Frame Description (详细描述): This dataset contains the CAD geometry and the extracted finite element matrices of the spatial multi-scale benchmark model presented in our paper. The compressed .zip archive consists of 69 files in total, specifically including: CAD Geometry: The 3D model provided in .stp format for general compatibility. Processed Matrix Files: Extracted structural matrices (e.g., stiffness and mass matrices) and node mapping files (.mapping) for the individual sub-components. Usage: Researchers can directly utilize these matrix files with custom scripts to: Assemble the global system matrices and calculate the natural frequencies. Generate the parametric super-element capsules. Perform interface dimensionality reduction using the Characteristic Constraint Modes (CCM). Conduct subsequent steady-state harmonic response and transient dynamic analyses. This dataset is provided to ensure full mathematical transparency and to facilitate the absolute reproducibility of the proposed energy-guided reduction and affine decoupling framework by the community.
