SIMSHIFT — Inspection Samples
This repository hosts a single representative simulation per task from the four SIMSHIFT datasets, for reviewer inspection only. The full datasets are hosted separately at simshift/SIMSHIFT_data.
These files are not intended for benchmarking, training, or any quantitative evaluation. They exist solely to let reviewers verify file format, schema, mesh structure, and output fields without downloading the full datasets (the heatsink set in particular is ~520 GB).
Contents
One sample file per task, in the same HDF5 format and schema as the full datasets:
| File | Task |
|---|---|
rolling_sample.h5 |
Hot Rolling |
forming_sample.h5 |
Sheet Metal Forming |
motor_sample.h5 |
Electric Motor Design |
heatsink_sample.h5 |
Heatsink Design |
How the samples were generated
Each file contains a single simulation drawn from the corresponding full dataset.The simulation is stored exactly as it appears in the full release, using the same HDF5 structure, field names, and units.
License
MIT, identical to the main SIMSHIFT release.
