Quick mode (Jasper) — 70+ components
Quick mode bundles 70+ validated components with property data sourced from NIST, DIPPR, Perry's Chemical Engineers' Handbook, and the RPP (Reid, Prausnitz & Poling) database. Each component includes:
- Critical properties (Tc, Pc, Vc)
- Acentric factors
- Wagner / Antoine / Lee-Kesler vapor pressure coefficients
- Cp polynomial coefficients
- NRTL BIPs for ~20 common pairs
This enables PR, NRTL, and Ideal calculations entirely in the browser.
Rigorous mode (DWSIM) — ~500 components
When you switch to Rigorous mode, Jasper hands the flowsheet to the DWSIM backend, which uses DWSIM's compound database (~500 compounds). Jasper components are resolved against DWSIM via CAS number first, then name, then formula. If a Quick-mode component isn't in DWSIM, the simulation fails with "Compound not found" — add a CAS number to the Jasper component to fix.
DWSIM's database supports cubic EOS (PR, SRK), activity coefficient models (NRTL, UNIQUAC, UNIFAC), IAPWS-IF97 steam tables, and DWSIM's electrolyte property packages.
