tetgen(1) A Quality Tetrahedral Mesh Generator

SYNOPSIS

tetgen [-pq__a__AriYMS__T__dzjo_fengGOJBNEFICQVvh] file

DESCRIPTION

This manual page documents briefly the tetgen command. Full documentation is available online: http://tetgen.berlios.de/

tetgen generates the Delaunay tetrahedralization, Voronoi diagram, and convex hull for three-dimensional point sets, generates the constrained Delaunay tetrahedralizations and quality tetrahedral meshes for three-dimensional domains with piecewise linear boundary.
 

OPTIONS

A summary of options is included below. For a complete description, see the online documentation.
 

-p
Tetrahedralizes a picecwise linear complex (.poly or .smesh file).
-q
Quality mesh generation. A minimum radius-edge ratio may be specifyed (default 2.0).
-a
Applies a maximum tetrahedron volume constraint.
-A
Assigns attributes to identify tetrahedra in certain regions.
-r
Reconstructs/Refines a previously generated mesh.
-Y
Suppresses boundary facets/segments splitting.
-i
Inserts a list of additional points into mesh.
-M
Does not merge coplanar facets.
-T
Set a tolerance for coplanar test (default 1e-8).
-d
Detect intersections of PLC facets.
-z
Numbers all output items starting from zero.
-j
Jettison unused vertices from output .node file.
-o2
Generates second-order subparametric elements.
-f
Outputs faces (including non-boundary faces) to .face file.
-e
Outputs subsegments to .edge file.
-n
Outputs tetrahedra neighbors to .neigh file.
-g
Outputs mesh to .mesh file for viewing by Medit.
-G
Outputs mesh to .msh file for viewing by Gid.
-O
Outputs mesh to .off file for viewing by Geomview.
-B
Suppresses output of boundary information.
-N
Suppresses output of .node file.
-E
Suppresses output of .ele file.
-F
Suppresses output of .face file.
-I
Suppresses mesh iteration numbers.
-C
Checks the consistency of the final mesh.
-Q
Quiet: No terminal output except errors.
-V
Verbose: Detailed information on what I'm doing.
-v
Prints the version information.
-h
Help: A brief instruction for using TetGen.

EXAMPLES

The wing is described in two files: wing.node and wing.poly. The command line:
  tetgen -pq wing
  generates the quality mesh in three files: wing.1.node, wing.1.ele, and wing.1.face.
 

Default, the radius-edge ratio of each tetrahedron is bounded below 2.0. You can impose a tight bound by adding a number directly after the '-q' switch. Like this:
  tetgen -pq1.2 wing
  generates a quality mesh which have more points inserted than the mesh created in above.
 

See http://tetgen.berlios.de/switches.examples.html for more examples.
