Computational Fluid Dynamics AI Evaluation Engineer

The Work

You will review and solve advanced computational fluid dynamics problems, then assess whether AI-generated technical answers are correct, accurate, and technically sound. Your feedback will help improve how AI systems interpret, solve, and explain engineering simulations.

The work includes practical simulation judgment, theoretical fluid-dynamics questions, troubleshooting, validation, and clear written and verbal explanations.

• Evaluate CFD problems involving mesh generation, turbulence models, multiphase flow, heat transfer, and solver configuration.
• Review AI-generated engineering responses for correctness, technical accuracy, and engineering integrity.
• Use mesh-independence studies, turbulence-model selection, boundary-condition checks, and convergence analysis to troubleshoot problems.
• Validate fluid-flow, heat-transfer, and multiphysics results against experimental or analytical data.
• Document feedback and explain technical findings clearly to support AI learning and performance.
