Water pump: generated with DWSIM 9.0.5 Automation3, Water / IAPWS-IF97, 20 C, 10 kg/s, delta P 300 kPa, efficiency 75%.
Methanol column: derived from DWSIM 9.0.5 tests/MethanolDistillation.dwxmz (GPL v3, Daniel Medeiros and contributors). Four simulation objects retained: preheated feed, distillate, bottoms, distillation column. Auxiliary units and legacy external energy connectors removed; internal condenser/reboiler equations retained.
Models are verification examples, not validated plant data. GPL v3 text is retained in DWSIM-license.txt and the repository LICENSE. Upstream provenance and modifications are described in THIRD_PARTY_NOTICES.md; the external engine is not distributed.

Integrated process: source-derived methanol column with a connected liquid pump, two-fluid UA preheater (hot water utility), feed pressure valve, product flash valve, and adiabatic vapor-liquid separator. Fixed feed composition 36 mol% Methanol / 64 mol% Water, source Raoult ideal-solution package. Builder: tools/build_dwsim_process.py. Engine coordinates and port connections are retained in the model and audited at run time.

Integrated process flash configuration: Inside-Out PH/PT, IO/NL fast mode disabled, internal and external tolerances 1e-9. An independent relative balance threshold of 1e-5 rejects unacceptable native results; solver success alone is insufficient.

Public release preparation removed nonphysical Settings/FilePath values containing local user paths from the two column-derived XML models. All other parsed XML content was checked unchanged. The native five-condition solve/balance acceptance was rerun on the sanitized files.
