AI Process Simulator

Is a steady-state chemical process simulator built in collaboration with Claude (Anthropic’s AI) using modern C++ (C++17/20) and Qt/QML. If you’ve used Aspen HYSYS or Aspen Plus it will feel familiar — you place equipment on a canvas, connect material streams, assign a fluid package, and specify each block by fixing a few variables and letting the solver find the rest. It currently models twelve unit operations — a rigorous distillation column (plus absorbers/strippers and a shortcut column), compressor/expander, heat exchanger, heater/cooler, pump, valve, mixer, splitter, two-phase and three-phase separators, and a recycle — with industry-standard thermodynamics (SRK, Peng-Robinson, PRSV, NRTL) and the full set of flash calculations. Columns solve the rigorous MESH equations, the flowsheet solves continuously as you work or on demand via an ordered Solve All, and recycle loops converge automatically. The column also has an embedded AI convergence advisor that can diagnose why a column won’t converge and suggest how to fix it. It’s an actively developed project, with more to come.

Windows may show a “Windows protected your PC” screen because the app is newly published — click More info → Run anyway to install. The download also includes 5 sample cases to try.

After downloading, you may need to make the file executable before it runs: right-click it → Properties → Permissions → tick “Allow executing file as program” (or in a terminal, chmod +x AI_Process_Simulator-1.3.0-x86_64.AppImage), then double-click to launch. No installation is needed — the AppImage runs as-is. The download also includes the same 5 sample cases to try.

If it still doesn’t start, install FUSE with sudo apt install libfuse2 (or your distro’s equivalent) and try again.
