Detailed Description

Triangle NETGEN 2D algorithm.

It can be created by calling smeshBuilder.Mesh.Triangle( smeshBuilder.NETGEN_2D, geom=0 )

This algorithm generates only 2D (faces) elements for given geometrical shape and, in contrast to NETGEN_1D2D_Algorithm class, should be used in conjunction with other 1D meshing algorithm.

Constructor & Destructor Documentation

◆ init()

def __init__	(	self,
		mesh,
		geom = `0`
	)

Private constructor.

Parameters

mesh	parent mesh object algorithm is assigned to
geom	geometry (shape/sub-shape) algorithm is assigned to; if it is `0` (default), the algorithm is assigned to the main shape

Reimplemented from NETGEN_Algorithm.

Reimplemented in NETGEN_2D_Remote_Algorithm.
