Procedure typically results in very well-shaped meshes.
The boundary by projections using the distance function. The boundary points are only allowed to move tangentially to The topology is regularly updatedīy Delaunay. Triangulation routine in MATLAB and tries to optimize the node locationsīy a force-based smoothing procedure. Interpolation between values on a grid, a common representation for levelįor the actual mesh generation, DistMesh uses the Delaunay More complicated geometries the distance function can be computed by A simpleĮxample is the unit circle in 2-D, which has the distance functionĭ=r-1, where r is the distance from the origin. The sign is negative inside the region and positive outside.
Shortest distance from any point in space to the boundary of the domain. One reason that the code is short and simple is that the geometriesĪre specified by Signed Distance Functions. Provided in our SIAM Review paper, see documentation below. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT.
