Dynovia Crash Open
200 vehicle crash simulation cases across sedans, an SUV, and pickup trucks, for building and testing crash prediction models.
Dynovia Crash Open gives engineers and researchers simulation data to develop, train, and evaluate their own models for non-commercial research. It covers five vehicle models, with multiple design configurations for each vehicle to capture variation in crash deformation.
Vehicle coverage
Each row shows a vehicle model; each column shows an example simulation case. The animation illustrates how different vehicle types and design configurations deform during a crash.
| Vehicle | Type | Simulation cases |
|---|---|---|
| Yaris | Sedan | 75 |
| Neon | Sedan | 20 |
| Rogue | SUV | 10 |
| Ram | Pickup | 30 |
| Silverado | Pickup | 65 |
| Total | 200 |
The design variants support studies of how structural design changes affect deformation over time. Engineers and researchers can use these cases to build surrogate models, test graph-based and neural operator methods, and evaluate predictions against simulation results.
Model prediction example
*An example Silverado simulation comparing our model, CrashFormer (Dynovia), with Transolver and GeoTransolver. The rows show simulation ground truth, model predictions, and spatial error in millimeters. Each model's RMSE is displayed as the simulation progresses.*
This example illustrates how the dataset can be used to inspect predicted deformation and its error over time.
Data format
Cases are organized by vehicle and case identifier. Each case includes:
| File or directory | Contents |
|---|---|
| animation.vtkhdf | Time-dependent mesh and simulation fields for visualization. |
| graph/ | Initial topology, connection definitions, and per-frame arrays for model development. |
To explore a case, open animation.vtkhdf in a VTKHDF-capable version of ParaView and play the time sequence. The coordinates already include deformation; do not apply an additional displacement warp.
For model development, start with the case's README.md, params.json, and manifest.json. Check simulation completion and use only the frames identified by valid_frame_count. Consult the case documentation for array alignment, units, and field availability.
Larger datasets and collaboration
Dynovia also offers crash_pro and crash_enterprise, each with thousands of simulation cases for broader exploration of crash behavior.
| Dataset | Design variables |
|---|---|
| crash_pro | Adds impact speed as an extra design variable. |
| crash_enterprise | Includes impact speed, geometry, and material as design variables. |
