OpenSeeSimE-Fluid-Mini

A stratified 1% subset of cmudrc/OpenSeeSimE-Fluid for evaluating vision-language models at a reduced compute footprint while preserving the joint distribution of simulation type, question type, media type, and question id.

Subset Provenance

Parent dataset: cmudrc/OpenSeeSimE-Fluid (98,326 rows total)
Rows in this subset: 1,040 (1.06% of parent)
Source classes: Bent Pipe, Converging Nozzle, Heat Exchanger, Heat Sink, Mixing Pipe
Parquet shards: 3 | Storage: ~11.61 GB
Sampling: per-stratum shuffle with numpy.random.default_rng(42), then take ceil(n * fraction) from each stratum. Any non-empty stratum contributes at least 1 row.
Strata: (source_file, question_type, media_type, question_id) — all four jointly.
Nesting: the 1% subset is a literal subset of the 10% subset (same shuffled prefix is taken for every fraction).

Composition

By `source_file`

source_file	rows	pct
Heat Exchanger	220	21.15
Mixing Pipe	220	21.15
Bent Pipe	204	19.62
Converging Nozzle	204	19.62
Heat Sink	192	18.46

By `media_type`

media_type	rows
image	520
video	520

By `(source_file, question_type)`

source_file	Binary	Multiple Choice	Spatial	Total
Bent Pipe	82	82	40	204
Converging Nozzle	82	82	40	204
Heat Exchanger	88	88	44	220
Heat Sink	76	72	44	192
Mixing Pipe	88	88	44	220

Feature Schema

Identical to the parent dataset. See cmudrc/OpenSeeSimE-Fluid for full documentation of simulation generation, ground-truth extraction, preprocessing, limitations, and intended use.

}

Intended Use

Benchmark evaluation of vision-language models on engineering simulation question answering at reduced compute cost
Smoke-testing of evaluation pipelines before running the full benchmark
Comparative studies where storage or bandwidth constraints matter
