TetGenGetNeighbors

TetGenGetNeighbors[expr]
gets the neighbors in a TetGen expression.

DetailsDetails

  • To use , you first need to load it using Needs["TetGenLink`"].
  • 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.
  • needs the "n" switch to be set during the call to TetGenTetrahedralize.

First, load the package:

In[1]:=
Click for copyable input

This creates an instance of a TetGen expression:

In[2]:=
Click for copyable input
Out[2]=

This sets up points and facets to use:

In[3]:=
Click for copyable input

This sets the points and facets in the TetGen instance:

In[4]:=
Click for copyable input

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

In[5]:=
Click for copyable input
Out[5]=

This extracts the points and elements from the tetrahedralization:

In[6]:=
Click for copyable input

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

In[7]:=
Click for copyable input
Out[7]=
