# SHIFT-NVH

Luminary released SHIFT-NVH, a large physics model trained on finite-element solves of a single body-in-white that takes the gauges of 15 parts, the material and the vehicle speed and returns RMS acceleration in x, y and z at all 130,713 surface nodes under ISO 8608 class B road excitation. On 192 test cases split by design, with material and speed unseen, the median relative L2 field error is 1.1% and the median part RMS error is 0.47%, about one tenth of the 5.4% median gauge-induced change. The model covers a fixed mesh, ±30% gauge, three materials and four speeds from 30 to 110 km/h, and final gauge decisions still rest on full FE and physical testing.
