Topics
- Traingulation data structure.
- Local mesh modifications by flips.
- Spatial sorting techniques.
- Efficient Robust geometric predicates.
- Symbolic perturbations.
This lecture will learn the following softwares for 2d and 3d mesh generation.
- Detri2 , A two-dimensional Delaunay mesh generator.
- TetGen, A three-dimensional Delaunay mesh generator.
The following (open source) softares will be used for visualization and comparison.
- Triangle, A two-dimensional Delaunay mesh generator.
- Gmsh, A three-dimensional finite element mesh generator with built-in pre- and post-processing facilities
- Paraview, an open-source, multi-platform data analysis and visualization application.
- Blender, an open-source, 3d modeling software.
We will use freefem++ to illustrate the basics of finite element methods and mesh adptation
- FreeFem++, an open-source, finite element software.
