{"name": "BlueMesh2D", "package_name": "BlueMesh2D", "description": "Generate unstructured triangular meshes from bathymetry rasters (BlueMesh2D)", "about": "Wraps the BlueMesh2D meshing library as QGIS Processing algorithms: from a bathymetry GeoTIFF to an unstructured triangular mesh, written as a UGRID NetCDF that loads directly as a QGIS mesh layer. The workflow runs as six stages:\n\u2022 1 - Extract the water polygon (coastline and domain) from the raster.\n\u2022 2 - Build a gradient-limited element-size raster: depth polynomial, wavelength (Hunt 1979) or a custom Python function, with optional finer detail regions.\n\u2022 3 - Resample the boundary to the element size, as an editable line layer.\n\u2022 4 - Generate the mesh: Delaunay or Frontal-Delaunay refinement, optional smoothing and smood orthogonalisation for Delft3D-FM.\n\u2022 5 - Classify the boundary nodes into open, closed and island, editable in QGIS.\n\u2022 6 - Export: UGRID NetCDF, Delft3D-FM open-boundary files (.pli / .bc / .ext) or ADCIRC .grd.\nEach stage produces an ordinary QGIS layer, so every intermediate result can be inspected and hand-edited before the next step; an all-in-one algorithm is also available for a single-dialog run.\nStep-by-step tutorial (PDF): https://github.com/GeoOcean/BlueMesh2D/blob/develop/docs/Tuto_BlueMesh2D_Santander.pdf\nDependencies need no manual setup. On first load the plugin detects what is missing and installs it in one click (Plugins \u25b8 BlueMesh2D \u25b8 Check / install dependencies). pip runs in QGIS's own interpreter; on Debian/Ubuntu system Python (PEP 668) the packages go into a plugin-managed virtual environment instead, leaving the system Python untouched. Installing bluemesh2d brings numpy, scipy, shapely, rasterio, matplotlib, netCDF4, xarray and triangle with it.", "homepage": "https://github.com/GeoOcean/BlueMesh2D/tree/develop/bluemesh2d_qgis", "repository": "https://github.com/GeoOcean/BlueMesh2D", "tracker": "https://github.com/GeoOcean/BlueMesh2D/issues", "author": "Geomatics and Ocean Engineering Group", "tags": ["adcirc", "unstructured", "mesh", "ugrid", "triangulation", "delft3d", "bathymetry", "ocean"], "downloads": 224, "latest_version": "0.1.4", "versions": [{"version": "0.1.4", "experimental": false, "qgis_min": "3.34.0", "qgis_max": "3.99.0", "downloads": 126, "uploaded_by": null, "upload_datetime": "2026-08-05T08:19:12.152831"}, {"version": "0.1.3", "experimental": false, "qgis_min": "3.34.0", "qgis_max": "3.99.0", "downloads": 41, "uploaded_by": "FaugereE", "upload_datetime": "2026-08-03T06:17:33.823649"}, {"version": "0.1.2", "experimental": false, "qgis_min": "3.34.0", "qgis_max": "3.99.0", "downloads": 57, "uploaded_by": "FaugereE", "upload_datetime": "2026-07-29T05:55:58.998790"}]}
