Clement Dumeril.

Mechanical engineer in industrial mechanics, simulation and robotics.

Arts et Metiers engineering student building a profile at the intersection of industrial mechanics, simulation, manufacturing and control. My work combines CAD design, finite element analysis, multiphysics simulation, machining, metrology, vibration theory, polymer behavior, laser-based experimentation and automation.

Across projects in industrial gearbox design, manufacturing studies, acoustic and vibratory systems, robotic cells and simulation-driven engineering missions, I connect physical modeling with practical technical execution. At UC Berkeley, I am extending this foundation toward robotics, AI and vision-language models.

01. Featured Missions and Applied Work

Cryogenic container temperature simulation

Cryogenic Container Mission

CAD (CATIA V5) - CFD (COMSOL) - Management (Team of 3)

Managed a team of three Arts et Metiers engineering students on a consulting mission for Airflow, focused on the development of a liquid nitrogen-based refrigerated container. The project aimed to maintain -3°C for 60 hours by optimizing the internal piping architecture. Delivered technical design recommendations and conducted a quality and regulatory analysis for the transport of perishable food products, supporting the future industrialization of the prototype.

Dream Extraction Lab interface for fiche idee extraction comparison

PJT - Idea Sheet Extraction Study

Fine-tuning - Hugging Face - VLM - DODO

LCPI and Arts et Metiers project partners logos

One-year research support project carried out with LCPI and Arts et Metiers to help a doctoral researcher study how engineering data can be extracted from both an idea-sheet diagram and its accompanying text in order to reconstruct a usable 3D model. We fine-tuned a DODO-based vision-language model on a reworked ABC library through Hugging Face, then compared that pipeline against several public large models to measure the impact of engineering-oriented prompting on extraction quality.

Type IV Hydrogen Bottle Prediction

PyTorch - Abaqus - CalculiX - Genetic algorithm

This project focused on correcting and restructuring a genetic algorithm used to predict rupture in a Type IV hydrogen tank. The workflow combined machine-learning logic with a DOE campaign generated from CalculiX simulations, then used that dataset to recalibrate the prediction pipeline and study failure trends across the vessel design space.
