0.5.1
- Security scan (Bandit) clean: errors the plugin works around are
written to the TELEMAC Toolkit log instead of ignored; the MMG call
runs only the mmg2d program you set (checked to be a program), with an
argument list and no shell
0.5.0
Meshing
- Meshing methods: Balanced and Quality-guaranteed (smallest angle 20
to 30 degrees); with the optional gmsh package Gmsh Delaunay,
Frontal-Delaunay, MeshAdapt and quadrilaterals; Compare meshing
methods (also meshes made in Blue Kenue or elsewhere)
- Mesh type in step 4: Triangles, Rectangles where drawn (structured
channels and grid zones) or Quadrilaterals everywhere (Gmsh)
- Sizes from the terrain (bed tolerance), element sizes as a raster,
sizes suggested from the DEM's pixels; breaklines from a DEM (crests
and toes)
- The mesh boundary follows the drawn outline within a set distance
(Follow the outline within; 5 percent of the element size by default);
digitizing zigzags no longer become nodes and slivers
- Node count estimated before meshing, with a node limit (2 million by
default, adjustable); about 20 percent faster on large meshes
- Optimise or adapt a mesh with MMG (shapes, terrain sizes, or sizes
from a TELEMAC result)
- Fixed: outlines digitized with many close vertices could hang
Generate mesh; vertices of rings far from the origin could be lost; a
domain edge in line with a channel end could loop forever; edge flips
could worsen the worst angle or change structured parts
Rivers and channels
- River reach helper: from a centreline (constant width or banks found
in a DEM) or two bank lines; river networks with confluences and
bifurcations; nodes across follow the width (at least 7);
cross-sections turned only in tight bends
- Channel templates composed from segments: straight, bends, elbows,
sine-generated and Kinoshita meanders, tapers and expansions, slopes
and drops; cross-sections rectangular, trapezoidal, compound, V,
parabolic, asymmetric or any formula
- Channels from a drawn centreline, or from TXT, CSV or DXF files (as
a centreline with widths, or as outlines)
- Structured cells cut along one diagonal (the shorter one in
channels), which stops TELEMAC's depths oscillating from node to node
Drawing and editing
- Check the drawing measures the geometry against the element size
(near-duplicate vertices, spikes, close corners, dense breaklines,
narrow gaps, line ends just off the outline, invalid polygons), shows
the problems on the map and fixes the safe ones; also as a Processing
tool
- Hover tips on every project layer (size, area, perimeter, nodes,
boundary codes), attribute forms with drop-down lists, snapping,
tracing and Advanced Digitizing set when a project opens; object
counts follow the drawing
- Edit a generated mesh in QGIS and rebuild it with every variable and
its .cli; re-mesh inside polygons; boundary lines from a .cli; Blue
Kenue lines (.i2s, .i3s) and meshes (.t3s) read
- Blue Kenue's boundary types and tracer codes (LITBOR) in the
boundary forms; custom codes
Run files and TELEMAC
- Run files (step 6): rating curve, liquid boundaries file (.liq) from
CSV or Excel, initial conditions (also depth above the channel axes),
steering file with a time step that divides the duration, NERD
advection and velocity profiles on discharge boundaries; warnings for
dry discharge boundaries
- SELAFIN coordinates kept exact in map coordinates (integer origin
above 4 km, 0.01 mm); double precision (SERAFIND) as an option,
declared in the steering file
- The whole chain tested in TELEMAC-2D v9.1 (meandering river, river
network, Gmsh mesh, re-meshed and edited meshes, laboratory expansion)
Fixes and other changes
- Generate mesh overwrites a mesh loaded in QGIS on Windows (before:
OSError Errno 22); the local laboratory grid is a named QGIS CRS; a
CRS without an EPSG code is matched to its EPSG equivalent
- Arrows follow the vector shown (velocity, unit discharge, wind);
calculator X/Y outputs drawn as arrows; calculator runs from
qgis_process
- New plugin icon; author name spelling
0.4.1
- Code quality: bottom formulas evaluated by a whitelisted expression
walker (no eval)
- Handled errors are logged to the TELEMAC Toolkit tab of the Log
Messages panel instead of ignored
- Flake8 clean-up (unused imports, ambiguous names)
0.4.0
- Arrow settings: grid spacing, proportional or fixed-scale length,
hide below, colour by magnitude
- Results open in view: CRS from a .prj or the project, or asked
(local or map CRS); zoom and CRS buttons
- Calculator: algebra, ddx, ddy, grad, div, curl, strain, Laplacian,
tmax, tmin, tmean, tint, tpeak, ddt
- Integrals and fluxes: discharge through sections, line and area
integrals, volumes
- Edit node values of a mesh: replace, add, raise, lower, inside
polygons; .cli kept
- Channel templates: straight flume, circular bend, sine-generated
meanders; bed formulas in s and n
- Liquid boundaries numbered exactly as TELEMAC numbers them
- Automatic default element size; legend without duplicates
0.3.0
- Mesh workflow panel; clearer project layers (0.2.0 projects still
open)
- Local coordinates and straight flume template; files shifted to (0,
0) with optional rotation
- Roughness zones; output to SELAFIN, 2DM, Gmsh, GiD, UGRID, MIKE 21,
ADCIRC and HEC-RAS layers
- Export or convert mesh; extract part of a mesh; find a node or
element by number
0.2.0
- Mesher: unstructured triangles with refinement, constraint lines,
fixed points and islands
- Structured channels and regular grids; interpolation from rasters
and points
- Boundary conditions from lines; mesh quality
0.1.0
- SELAFIN read/write library; results as styled mesh layers, 2D and 3D
- Results panel with the Temporal Controller; live cursor, time
series, animated profiles
- Processing tools: file information, 2D from 3D, subset, time series
at points, mesh boundary
