Flowstead v3.2.2

Flowstead v3.2.2 (app version 3.2.2).

Phase envelopes you can trust

• Phase envelope: for some rich gases and condensates DWSIM traces the bubble and dew curves as two pieces that never meet. The app used to report the end of the bubble curve as the critical point and the cricondenbar, below dew points the PVT laboratory finds. It now says the envelope did not close and shows no critical point, cricondenbar or cricondentherm for it; the curves are still drawn as DWSIM traced them.
• Vapour-fraction (quality) lines: near the critical point DWSIM's flash could give up and return a made-up temperature, which drew a stray line across the plot. Every point is now checked with a second flash, and a line stops where the flash stops working.

Install: download flowstead-v3.2.2.apk on your Android phone (Android 8.0 or newer, 64-bit), open it and allow installing from this source.

Coming from a 0.x test build? Those were signed with the public debug key and this release is signed with the release key, so Android can't install it over them: export each project you want to keep (project menu → Export DWSIM file), uninstall the old app, install this one and import the files (Projects → Import DWSIM file). Data-sheet fields and line-sizing criteria are not part of a DWSIM file. Later releases install as updates.

Solves on the phone: DWSIM runs on the device (Settings → Engine → On this phone, the default); the first solve after starting the app takes a few seconds while DWSIM loads. A remote Flowstead engine (docs/engine-setup.md) is optional.
