CVT_TET_MESH is a FORTRAN90 program which applies CVT methods to produce a tet mesh of various test regions in 3D.
Note that, when using this program, we begin with a region, which is to be filled up with a number of (unspecified) points and then organized into tetrahedrons.
Other programs, such as TABLE_TET_MESH, are available for the case where the points are already given, and only the tetrahedrons need to be determined.
The CVT points are written to files in the TABLE format.

P01 is the 3x1x1 channel. Test files you may copy include:
We also ran problem P01 with several sizes, using the test #3 code (some points are forced to lie on the boundary, and some points are specified by the user.) These three sets of points where then used in other calculations, the first of which is TABLE_TETRA, which computes a "tetrahedronalization" of the points.
P02 is the vertical cylinder. Test files you may copy include:
