About the Job

Requirements

  • Currently pursuing a BAC+5-level course of study in numerical mechanics or applied mathematics.
  • Have skills in numerical mechanics or simulation, including finite element simulation and solving partial differential equations.
  • Have knowledge of applied artificial intelligence and machine learning, including neural networks, surrogate models, optimization, and performance metrics.
  • Understand parametric problems, including surrogate modeling and multi-scenario validation.
  • Have programming skills in Python; workflow automation and data analysis are desirable.
  • Have ideally used simulation and optimization workflows, such as ANSYS or OptiSLang, or equivalents.
  • Have knowledge of scientific machine learning or physics-aware machine learning, with PINNs as a comparison component.
  • Demonstrate rigor and autonomy.

Responsibilities

  • Conduct a structured literature review of PINNs and physics-informed machine learning approaches for solving partial differential equations in mechanics.
  • Set up evaluation campaigns for vibratory mechanics use cases, comparing a reference solver with AI or surrogate solutions.
  • Compare computational time, accuracy on fields or indicators, and robustness to parameter variations.
  • Experiment with sampling techniques to optimize learning and sampling strategies.
  • Validate scientifically and compare against baseline data-driven machine learning models, classical surrogate models, or a reference numerical solver when available.
  • Iteratively improve models, including their architecture, training, and hyperparameters.
  • Prepare progress summaries, document assumptions, write technical deliverables, and present results.

Desired Qualifications

  • Experience with simulation and optimization workflows, such as ANSYS or OptiSLang, or equivalents.
