In this work, we compare a traditional design-ofexperiments (DoE) workflow, defined up-front and then run, against an agentic AI workflow that revises its plan as the data arrives. The use case is a chassis optimization on the standard compact example in the Modelon VehicleDynamics Library. Both workflows produce a recommendation. The DoE arrives at a clean Pareto front and a stiffness change. The agentic path is longer: along the way it flags a controller saturation in the DoE winner, traces a center-ofgravity asymmetry to a load sensitivity the original scope did not cover, and finds a kinematic ceiling outside the four DoE parameters. It ends up changing a different parameter, and that parameter turns out to do more than the static KPIs asked for: dynamic verification shows the bushing change roughly halves the fishhook return lag unloaded. The architecture that makes this possible combines validated physics, Modelon Impact, the Model Context Protocol that connects them to an LLM, and a knowledge base layered by lifetime. We close with what we learned about when each approach is the right tool.
Clément is leading the Technology Cluster for Digital Mechatronics at Siemens Healthineers. He is responsible for building up a team of experts in digitalization - where the scope ranges from modeling and simulation, Scientific Machine Learning, to Artificial Intelligence -, and triggering and leading technological projects to enhance the development of Siemens Healthineers mechatronic products and their digital capabilities. This role leverages the past experiences of Clément as a Team Lead and Model-based Development expert at Modelon and at other industry leaders such as Airbus Helicopters and Dassault Systèmes. Clément holds two MSc - in France and Spain - in System Engineering and Mechanical Engineering, and a PhD on model-based hydraulic actuation system design for helicopters.
Clément started leveraging Modelica in 2008 and has not stopped since then. He joined in May 2026 the Boad of the Modelica association, with the specific duty to advance and shape the future of the technology.
Clément is a happy husband and father of two amazing boys - who are making his life even more exciting than his work.
