Alternative mesh generation for Landlab
Jay Hariharan at University of Texas at Austin.
This lab consists of three notebooks that use the mesh generator dmsh and the mesh generator from Anuga to create unstructured grids that are passed into Landlab. The examples contain code for creating Landlab models using these other mesh generators as a starting point. Only the flow accumulation and drainage area components are demo'd, but there are many other questions one might want to ask about the influence of cell resolution (and local cell resolution) on different landscape evolution processes.
This lab is designed for undergraduate and graduate students studying earth sciences. The notebooks give participants the opportunity to interactively explore the topics covered.
- Mesh generation in dmsh, Anuga, and Landlab
- Mesh generation
- Mesh visualization
More information on the examples used in this lab can be found in the documentation: https://elbeejay.github.io/meshing-with-landlab/. The source code for the examples can be found at https://github.com/elbeejay/meshing-with-landlab.
If run locally, this lab requires the installtion of the Python packages numpy, matplotlib, landlab, dmsh, anuga, itkwidgets, and pyvista. See https://jayaramhariharan.com/meshing-with-landlab/dependencies for more detailed installation instructions.
