Stage - Ingénieur Biomécanique Numérique h/f

Founded in 2014, Sim&Cure is French digital start-up focused on improving neurovascular treatments of cerebral aneurysm with a proprietary software suite. The Sim&Size™ software is a Class II medical device with CE mark and FDA clearance that has already been used to treat more than 10,000+ patients in 500+ hospitals in the world.

Through several modules, Sim&Size™ is a software suite that provides to the physician a 3D visualization of medical images and a computational model of neurovascular implantable medical devices (IMDs). The therapeutic strategy is the most important step of this disease treatment and Sim&Size™ is now part of it by being efficient, safe, and reproducible. Computational modeling of specific devices in the anatomy of a patient helps the physician to achieve the intended outcome of the intervention.

This internship will be carried out within the Biomechanics team, contributing to the improvement of the FDsize module, dedicated to the simulation of flow diverters. Flow diverters are a key treatment option for complex cerebral aneurysms, and reliable patient-specific simulations play an important role in treatment planning and decision-making.

Missions

The FDsize module is responsible for simulating the deployment and behavior of flow diverters and currently relies on a proprietary algorithm developed in-house. The Biomechanics team is improving the design of this module. The aim of the internship is to develop a finite element (FE) model for simulating flow diverters using the company’s in-house solver. This FEM model will serve the objectives defined for improving FDsize module and needs to be compliant with Sim&Size™ design criteria.

Objectives:

• Finite Element Simulations: Develop and run FE simulations of flow diverter deployment, post-process results, analyze key performance indicators, and refine the model to meet product design objectives.

• Validation: Contribute to verification and validation studies using the new model to assess its credibility.

Required Skills and Competencies:

• Finite Element Modeling

• Python Programming

• Post-processing of simulation results (experience with ParaView or equivalent)

• Knowledge of Solid Mechanics / Mechanical Engineering

• Analytical Thinking & Problem-Solving Skills

• Familiarity with C++ is a plus

• Familiarity with validation and experimental methods
