NAME
tetgen — 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.
