Syntax

TR = triangulation(gm)

Description

TR = triangulation(gm) creates a triangulation object from the specified fegeometry object. The geometry must have one cell in 3-D or one face in 2-D.

Create a 2-D triangulation object from the unit square geometry.

First, create an fegeometry object representing the unit square.

gm = fegeometry(@squareg)
gm = 
  fegeometry with properties:

       NumCells: 0
       NumFaces: 1
       NumEdges: 4
    NumVertices: 4
       Vertices: [4×2 double]
           Mesh: []

Create a triangulation object from the fegeometry object.

TR = triangulation(gm)
TR = 
  triangulation with properties:

              Points: [48×2 double]
    ConnectivityList: [46×3 double]

Create a 3-D triangulation object from a cylinder.

First, create an fegeometry object representing a cylinder.

gm = fegeometry(multicylinder(5,2))
gm = 
  fegeometry with properties:

       NumCells: 1
       NumFaces: 3
       NumEdges: 2
    NumVertices: 2
       Vertices: [2×3 double]
           Mesh: []

Create a triangulation object from the fegeometry object.

TR = triangulation(gm)
TR = 
  triangulation with properties:

              Points: [98×3 double]
    ConnectivityList: [192×3 double]

Input Arguments

collapse all

Single-domain geometry, specified as an fegeometry object. If you specify a 2-D geometry, it must have one face. If you specify a 3-D geometry, it must have one cell.

Output Arguments

collapse all

Triangulation, returned as a triangulation object. For details, see triangulation.
