Agent
Runs closed-loop, agentic optimization of a large already-built multi-area NeqSim ProcessModel plant (offshore separation + recompression + export trains) across one or more years/scenarios. Drives operating setpoints (compressor pressures, heater/cooler temperatures, stage pressures, routing fractions) using the…
Agent
Routes PaperLab writing and publishing requests for NeqSim papers, scientific manuscripts, journal submissions, book chapters, textbooks, reproducibility packages, figures, references, and reviewer responses. Use this as the single VS Code Chat entry point for PaperLab instead of exposing every PaperLab internal agent.
