TetGenGetNeighbors

TetGenGetNeighbors[expr]

gets the neighbors in a TetGen expression.

Details and Options

  • To use TetGenGetNeigbors, you first need to load it using Needs["TetGenLink`"].
  • TetGenGetNeigbors returns a list of a list of integers that specify which tetrahedra are next to each other. An entry of indicates that the respective tetrahedron is on the boundary.
  • TetGenGetNeigbors needs the "n" switch to be set during the call to TetGenTetrahedralize.

Examples

Basic Examples  (1)

First, load the package:

This creates an instance of a TetGen expression:

This sets up points and facets to use:

This sets the points and facets in the TetGen instance:

This carries out the tetrahedralization, returning a new TetGen instance. The switch "n" requests TetGen to compute the neighbors:

This extracts the points and elements from the tetrahedralization:

This is a list of the neighboring elements, with indicating a boundary:
