MaximaLabs vs. Legacy Process Simulators
Why modern engineering teams are moving off 1990s desktop architectures to an edge-native Process OS.
For decades, process simulation has been trapped on rigid desktop installations tied to license servers and disconnected, offline workflows. MaximaLabs runs in the browser, deploys its real-time control engine to edge gateways, and keeps the whole team on one live flowsheet instead of emailing files back and forth.
| Capability | MaximaLabs | Legacy Desktop Simulators |
|---|---|---|
| Thermodynamics & engineering | ||
| Thermodynamics | ✓ PR, SRK, PC-SAFT, CPA, SAFT-VR Mie, NRTL, UNIQUAC, Wilson, eNRTL, GERG-2008, steam, polymer & brine electrolyte — plus Ge mixing rules (PSRK, MHV1, Huron-Vidal) and selectable predictive UNIFAC / modified UNIFAC (Dortmund) for pairs with no fitted binary | Similar, but siloed apps |
| Unit-op library | ✓ 100+ unit ops in one canvas — reactive & dividing-wall columns, 3-phase decant, a solids train, biologics downstream (TFF, Protein A, viral clearance), batch recipes and API 520/521 relief | Comparable, desktop-bound |
| Transparency | ✓ Click any block → the equations it solves | Black box |
| Cost & sizing | ✓ Screening cost + HX rating in the flowsheet | Separate ACCE / EDR apps |
| Control & operations | ||
| Dynamics & control | ✓ MIMO DMC (MaximaLabs dynamic execution, feedforward, multi-rate, bad-sensor shedding) on one canvas | Separate dynamics license |
| Plant integration | ✓ Digital twin + data reconciliation | Bolt-on / none |
| Sustainability | ✓ Scope 1/2/3 + carbon-tax on any flowsheet | Add-on / none |
| Architecture & workflow | ||
| Access | ✓ Any browser, zero install | Desktop install + license server |
| Enterprise SSO | ✓ Self-serve SAML 2.0 (Okta/Azure AD/Ping) — configure it yourself in minutes | Bolted on via a paid professional-services integration |
| Deployment model | ✓ Hosted, or fully self-hosted on your own network — your choice | On-prem desktop only, per-seat license server |
| Interface | ✓ Modern, fast canvas | 2003-era Windows UI |
| Convergence errors | ✓ AI explains the cause + the fix Unique to MaximaLabs | Cryptic numeric codes |
| Collaboration | ✓ Live multiplayer + share links Unique to MaximaLabs | Email .hsc files around |
| Onboarding | ✓ ~30 minutes | ~3-day training course |
| Pricing | ✓ Usage-based, ~1/10th the cost | Six-figure seat licenses |
| Automation | ✓ Python SDK + Excel add-in (=FLOWSIM.RUN) | Bolt-on / COM automation |
