0.2.0
- Cross-platform install fixes. The manual fallback commands shown in
the
dependency dialog now quote every requirement: unquoted,
"bluemesh2d>=0.1.8"
is a redirection in cmd, PowerShell, bash and zsh and installed the
unpinned package.
- Packages installed by the dialog now take precedence over older
copies
in the system site-packages (e.g. Ubuntu's python3-shapely 1.8), which
used to shadow them so the upgrade changed nothing.
- The plugin virtual environment (Debian/Ubuntu, Homebrew) is built
with a
real Python interpreter. Where QGIS provides none (macOS:
sys.executable
is the QGIS application) pip runs in QGIS itself instead of launching
a
second QGIS.
- Windows: no console window flashes up during installation, the venv
interpreter is looked up as python.exe, and a missing pip gets an
OSGeo4W-specific hint. Linux: the missing-pip hint also covers Fedora
and
Arch.
- Export 6a no longer fails when the output is the same file as the
input
spelled differently (drive-letter case, or file-name case on Windows
and
macOS); mesh layers are located through their provider instead of by
splitting the URI.
0.1.9
- Fix "hfun raster failed: module 'shapely' has no attribute
'prepare'"
(seen on macOS, where QGIS ships Shapely 1.x): the library needs
Shapely 2.0 or newer.
- Fix "module 'numpy' has no attribute 'bool'" (boundary
classification
and any stage reading the mesh) on machines whose QGIS Python has an
old netCDF4 next to NumPy 1.24 or newer.
- The dependency check now verifies minimum versions of shapely (2.0),
netCDF4 (1.6.4), xarray (2023.1) and scipy (1.10), not just that they
are present; the install button upgrades any that are too old and the
dialog lists which ones.
0.1.8
- ADCIRC .grd export: the nodes of each element are now sorted
clockwise
before writing, as the .grd format requires.
- Requires bluemesh2d 0.1.8 or newer for the sorted export.
0.1.7
- Stage 2 / all-in-one: new option "Clip to the water polygon". The
size
function is now clipped to the stage-1 polygon itself, not just to its
bounding box: outside it the size is the neutral maximum, so land
pixels
no longer drag the element size of the water down through the gradient
limiting. On a 100 m deep channel next to flat land the elements 1 km
offshore were 200 m instead of the 4200 m the depth asks for; they are
now 4200 m. Untick the option for the previous behaviour.
- Slope refinement no longer straddles the coastline: the depth
gradient
is evaluated one-sided when a sample falls on land, instead of
subtracting a land elevation from a sea depth and inventing a huge
gradient that produced tiny elements along the shore.
- Check / install dependencies now reports whether the installed
bluemesh2d is the latest release on PyPI, and offers to upgrade. The
query runs only when the dialog is opened, never on plugin load, and
every failure (offline, proxy, timeout) is ignored silently.
- Requires bluemesh2d 0.1.7 or newer for the clipping option.
0.1.3
- Stage 4 / all-in-one: new smood option "merge the remaining
problematic
elements during recovery", on by default from recovery cycle 2. A mesh
whose last few small flow links sit on nodes smoothing may not move
(fixed points, boundary vertices) now completes instead of failing
with
"mesh still violates dual criteria". The recovery cycle it starts at
is
an advanced setting; untick the option for the previous behaviour.
- The smood progress table gained an N_MERGED column, so it is visible
whether a recovery cycle merged anything.
- Declares its Python dependencies (bluemesh2d, pyproj) in the
metadata,
so they are listed on the plugin page.
- Clearer About text: the six stages as a bullet list.
0.1.2
- First public release.
- The meshing library is installed from PyPI (bluemesh2d) instead of
being
bundled with the plugin: one dependency to install, and library fixes
reach users without a plugin update.
- One-click dependency installer: detects what is missing on load and
installs it into QGIS's own Python, or into a plugin-managed virtual
environment on PEP 668 systems (Debian/Ubuntu).
- Qt6-compatible scoped enums throughout; requires QGIS 3.34 or newer.
0.1.0
- Initial release: 6-stage Processing workflow from bathymetry raster
to
UGRID NetCDF, plus an all-in-one algorithm.
