TetGen Analysis Interface Module (AIM)
|
This is the output from executing "tetgen -h" on command line.
Parameter | Description |
---|---|
-p | Tetrahedralizes a piecewise linear complex (PLC). |
-Y | Preserves the input surface mesh (does not modify it). |
-r | Reconstructs a previously generated mesh. |
-q | Refines mesh (to improve mesh quality). |
-R | Mesh coarsening (to reduce the mesh elements). |
-A | Assigns attributes to tetrahedra in different regions. |
-a | Applies a maximum tetrahedron volume constraint. |
-m | Applies a mesh sizing function. |
-i | Inserts a list of additional points. |
-O | Specifies the level of mesh optimization. |
-S | Specifies maximum number of added points. |
-T | Sets a tolerance for coplanar test (default 1e-8). |
-X | Suppresses use of exact arithmetic. |
-M | No merge of coplanar facets or very close vertices. |
-w | Generates weighted Delaunay (regular) triangulation. |
-c | Retains the convex hull of the PLC. |
-d | Detects self-intersections of facets of the PLC. |
-z | Numbers all output items starting from zero. |
-f | Outputs all faces to .face file. |
-e | Outputs all edges to .edge file. |
-n | Outputs tetrahedra neighbors to .neigh file. |
-v | Outputs Voronoi diagram to files. |
-g | Outputs mesh to .mesh file for viewing by Medit. |
-k | Outputs mesh to .vtk file for viewing by Paraview. |
-J | No jettison of unused vertices from output .node file. |
-B | Suppresses output of boundary information. |
-N | Suppresses output of .node file. |
-E | Suppresses output of .ele file. |
-F | Suppresses output of .face and .edge 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, more terminal output. |
-h | Help: A brief instruction for using TetGen. |
