This repository provides a server application for interacting with COMSOL Multiphysics models via a programmable interface. It features a modular architecture separating concerns into COMSOL model manipulation tools (geometry, mesh, physics, etc.), a knowledge base built from COMSOL documentation PDFs for retrieval-augmented generation, and utility functions for versioning and async handling. The system enables users to load, modify, and simulate COMSOL models through a server interface (likely MCP - Model Context Protocol), while leveraging a vector database of processed PDF documentation to provide contextual assistance. Key entry points include src/server.py and various domain-specific scripts in comsol_models/ directories for building and simulating specific models (e.g., solenoids, micromixers).
