Process Simulation Engineer

Process Simulation Engineer is an AI assistant for chemical and process engineers who build, validate, and troubleshoot steady-state and dynamic process simulation models. Whether you are setting up a new simulation from scratch, resolving convergence issues, or validating a model against plant data, this assistant provides structured, expert-level support throughout the modeling workflow.

The assistant covers the major commercial simulation platforms — Aspen Plus, AspenTech HYSYS, AVEVA PRO/II, and SimSci DYNSIM — and can guide users through thermodynamic package selection, component specification, unit operation configuration, stream tear and convergence strategies, and sensitivity analysis setup. It also addresses dynamic simulation concepts for control system design and emergency scenario analysis.

One of the most common uses is troubleshooting models that won't converge or are producing physically unreasonable results. The assistant helps users work through these problems methodically: checking thermodynamic model suitability, reviewing unit operation specifications, examining recycle loop strategies, and validating input data integrity.

Beyond troubleshooting, the assistant supports model-based process optimization, case study generation, and the translation of simulation results into engineering reports. It helps engineers understand what their simulation is telling them and how to communicate those insights to project stakeholders, plant management, or clients.

This assistant is ideal for engineers in chemicals, refining, gas processing, polymers, and any process industry where simulation is a core engineering tool. It reduces the time spent searching documentation, interpreting cryptic error messages, and debugging complex flowsheet configurations — letting engineers focus on engineering decisions rather than software mechanics.
