Helmholtz Filter and Projection Parameter Validation Data for Topology Optimization

Abraham Vadillo Morillas deposited MATLAB code and validation datasets to reproduce results for a journal article under review. The repository includes raw one-dimensional sweeps, two-threshold surface sweeps, mesh-resolution studies, and records from a 5,600-case two-dimensional validation campaign. The data supports a methodology for independently prescribing minimum solid and void length scales in robust three-field topology optimization.

Use Cases

• Validating closed-form Helmholtz filtering maps for solid bars and void gaps based on the described methodology.
• Auditing the parameter-selection recipe for minimum length scales using the included validation and audit scripts.
• Reproducing accuracy statistics and figures from the paper, such as the reported median error of 0.54%.
• Studying the effects of mesh resolution, projection sharpness, and boundary clearance on topology optimization results.

Strengths

• Includes a 5,600-case two-dimensional validation campaign covering features like straight/curved ligaments and T/Y/X junctions.
• Provides the complete datasets used in the paper, enabling full reproducibility of figures, tables, and accuracy statistics.
• Contains a reference robust three-field MATLAB implementation alongside the raw data sweeps and studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
