Ocean mesh generation

Project description

Seamsh is a Python library wrapping gmsh, gdal and scipy to simplify the generation of unstructured meshes. While primarily developed for coastal ocean simulations, it can be used in other GIS contexts.

Main Features :

  • Import ESRI shapefiles to define tagged domain boundaries, interior lines and interior points.
  • Define arbitrary mesh elements size fields based on distances from lines or raster files.
  • Create a low-resolution valid topology from high-resolution non-conformal (i.e. intersecting) data.

Seamesh is distributed under the GPL. See the project gitlab page for the source code and bug reports. The documentation contains examples, Python API reference and installation instructions. Binary packages for 64 bits linux, windows and OSX are available on pypi.

Changes

seamsh 0.4.0

  • precompute and smooth mesh size field on a quadtree-like mesh
  • build library directly from setup.py, no cmake anymore
  • discretize curves in their own projection, not in the model projection
  • handle intersection of more than 2 interior curves on the same point
  • source distribution on pypi
