A Dassault Systemes Case Study
Wölfel, the German Seating Comfort and Biomechanics team in Höchberg, faced the challenge of predicting and optimizing vehicle-seat comfort and vibration-induced health effects without relying on expensive physical prototypes. To simulate complex human–seat interactions they used Abaqus FEA from SIMULIA — a Dassault Systemes product — together with their CASIMIR human‑body model.
Using Dassault Systemes' Abaqus, Wölfel enhanced CASIMIR with detailed anatomical continuum and discrete muscle models and ran static seating‑pressure and dynamic vibration analyses; the results correlated well with physical measurements, identified a problematic resonance near 5 Hz, and informed seat design changes used by OEMs such as BMW, Mercedes‑Benz and Ford. The approach significantly reduced prototype needs and cost (single hardware seats cost €10,000–20,000 and take days–weeks to build) by enabling model setups in under a day, speeding design iterations and lowering development risk.
