A new research paper explores the effectiveness of large language models (LLMs) as calibration agents for expensive engineering simulators. The study found that LLMs, when prompted with physics-based error descriptions, can initially propose more informative parameter updates than traditional derivative-free optimizers. However, this advantage diminishes over time and due to LLM variability. A hybrid approach, using the LLM to warm-start a conventional optimizer, proved most efficient, achieving target accuracy with significantly fewer simulator runs. AI
IMPACT LLMs may offer a more efficient approach to calibrating complex engineering simulations, potentially reducing computational costs.
