One flowsheet, from first design to live plant
Everything a process simulator does — plus the AI, the collaboration, and the digital twin — built on a single unified stream and flowsheet model, not five separate apps stitched together.
What makes this a different category of tool
Four decisions that shape everything else on this platform.
The solver always produces the number
The AI copilot reads simulation state, proposes flowsheets, and explains failures — it never computes a result itself. Every stream value comes from the deterministic Python solver, not a language model.
One data model, every consumer
A stream is the same object in the simulator, the reports, and the digital twin. No format conversion between tools, no drift between what you designed and what you're monitoring.
Rigorous thermodynamics, no black box
Peng-Robinson, NRTL, UNIQUAC, Soave-RK, IAPWS steam tables, and electrolyte NRTL — validated against published VLE data, not tuned to look right.
Browser-native, real-time collaboration
Zero install, live multiplayer on the same canvas, and a solve that keeps running even if you close the tab — versus emailing .hsc files back and forth.

One model, every way to solve it
The architecture that sets AVEVA Process Simulation apart from legacy sequential simulators — matched capability-for-capability, and running in your browser today.
One model, three solve modes
Steady-state, pressure-driven (Cv/Darcy resistances with pumps, compressors and turbines on real curves), and dynamic (holdup DAE) — all from the same flowsheet, toggled without re-authoring.
Equation-oriented simultaneous solver
Solve every stream unknown at once — no tearing — for tight recycle loops, alongside classic sequential-modular. The symbolic path emits exact analytic Jacobians.
Reusable Fluids & hierarchical sub-flowsheets
Define a Fluid once — composition plus property method — and reference it everywhere; collapse a subsystem into a reusable sub-flowsheet block and drill in to edit it. A project-level Fluid library shares them across models.
Progressive fidelity
Swap a column between a fast Fenske-Underwood-Gilliland shortcut and a rigorous MESH solve on the very same node — screen quickly, then refine, with no re-modeling.
Rate-based separations
Maxwell-Stefan two-film columns with published tray and packing mass-transfer correlations, a high-flux correction, and a coupled interface energy balance — for the absorption and reactive separations equilibrium stages get wrong.
Scenarios & case studies
Compare named scenarios side by side and sweep any parameter — each a full re-solve on the same model — to explore a design without forking it.
Every capability here is shipped and running in the browser today. Where a model is screening-grade rather than fully rigorous, we say so in the app — we disclose scope instead of implying databank depth we don't have.
