Flowstead v3.0.1

Flowstead v3.0.1 (app version 3.0.1).

Solves fast again

• 3.0.0 made a simple solve slow: two plain streams could take over 13 seconds on a phone, against about a second before. The cause was the new bubble- and dew-point check, which searched for a phase boundary with many extra flashes whenever DWSIM's answer did not check out. The search is gone: a bubble or dew point that does not check out is shown as missing (—), never as a wrong number. Pure compounds (water, steam) take DWSIM's vapour-pressure curve directly.
• Bubble and dew points of streams that did not change are remembered between solves, so editing one part of a flowsheet no longer recalculates them for every stream.

Install: download flowstead-v3.0.1.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.
