Millions of elements.
Zero invented results.
physicsbase ingested the public 2.27-million-element Toyota Camry crash model, verified its archive byte-for-byte, and built an OpenRadioss execution path. This page separates that full-vehicle reference from the smaller impact case actually executed on the available four-core worker.
Interrogate the solver evidence
The interactive field below is a physicsbase-native, verification-checked static solve of a representative bumper crush beam — a 3D hex8 solid mounted at both crash-rail ends under a central barrier load. It is our own result, orbitable and colour-mapped. It is deliberately separate from the full-vehicle Camry run, whose OpenRadioss-derived spatial fields stay licence-withheld; that run appears here only as the interrupted energy trace.
What was actually done
Full vehicle: ingested
The 63.6 MB CCSA archive was downloaded and matched its published SHA-384. The expanded 288 MB deck contains vehicle geometry, materials, 1,106 parts, instrumentation, initial wheel/vehicle velocity and contact definitions.
HASH VERIFIEDComponent impact: traced
OpenRadioss Starter completed with zero errors and one initial-penetration warning. Engine advanced 14,900 cycles at a 0.001 ms step; the last reported energy error was −0.1% and relative mass change was 2.1151×10⁻⁴. The session cap interrupted the run before its declared end.
INTERRUPTED TRACEFull crash: gated
The official OpenRadioss case page estimates roughly 60 hours on four cores. This worker had about 2.65 GB available RAM. physicsbase rejected a full launch rather than produce a partial or fabricated “completed crash.”
HPC REQUIREDRepresentative component: solved
Rather than fabricate a full-vehicle field, physicsbase solved a representative bumper crush beam with its own verified solver — a 3D hex8 solid, both ends mounted, central barrier load. The result above is that solve: real geometry, real von Mises and displacement, self-check verdict attached. It is a component demonstration, not a Camry crash.

Multiphysics and multiscale scope
The implemented workflow contract links a macro explicit crash to plastic-work-driven adiabatic heating, critical-zone submodel extraction, and coupon/RVE material calibration. Those transfers require a completed macro result plus conservation and mapping checks. No Camry temperature, residual-stress or damage field is published here until those prerequisites exist.
