ChronoLLM: A Framework for Customizing Large Language Model for Digital Twins generalization based on PyChrono

Project Chrono [1] is an open-source, physics-based simulation framework that supports the modeling, simulation, and analysis of complex systems. It is designed for high-performance, high-fidelity simulations and is widely used in research and industry. PyChrono [2] is the Python wrapper for Project Chrono, providing a user-friendly interface to the core functionalities of Project Chrono. It allows users to leverage the power of Project Chrono using Python, making it accessible to a broader range of users who prefer scripting in Python over C++. Project Chrono encompasses a wide range of features, and PyChrono inherits a subset of these capabilities: 1. Chrono::Engine: Provides core functionality for multibody dynamics and nonlinear finite element analysis, with robust treatment of friction and contact using both the penalty method and the Lagrange-multiplier method.
