SGmeshtetrahedron
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - FEM/PDE
Introduced first in SolidGeometry 4.7, Creation date: 2019-07-30, Last change: 2025-09-14
creates a tetramesh of a Solid Geometry - same as SGmeshtetrahedron
Description
USE SGshortopti before to remove oben boundaries and non manifold vertices
This function uses the importGeometry and generateMesh functions of the PDE-Toolbox to create a mesh of the solid an creates a triangualatin from this data.
ATTENTION: SGtetramesh WILL NOT MELT SEPERATED SOLIDS, They are still independent surfaces
In contrast to the normal PDE mesh, the linear mode is used here to create the 4-facet meshes directly
If SGtetramesh fails with error: "The input mesh is invalid" => SGcheckmeshlab
If SGtetramesh fails with error: "Meshing failed with a Hmax of" => Self intrusion!

Syntax
[SGn,VL,FL,TR]=SGmeshtetrahedron(SG,[h])
Input Parameter
SG: | | Solid Geoemtry |
h: | | maximum mesh length; default is sofBB/20 |
Output Parameter
SGn: | | Solid Geoemtry based on a PDE mesh |
VL: | | Vertex list |
FL: | | Facet list |
TR: | | Tetrahedron triangulation |
Examples
SGtetramesh(SGsample(17))
SGtetramesh(SGsample(17),3)
SGtetramesh(SGsample(35)) % failes because of non manifold
SGtetramesh(SGsample(36)) % failes because of self intrusion
