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

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

Member Function Documentation

def MaxElementArea	(		self,
			area,
			UseExisting = 0
	)

Defines MaxElementArea parameter of hypothesis basing on the definition of the maximum area of each triangle.

Parameters

area	maximum area value of each triangle
UseExisting	if True - searches for an existing hypothesis created with the same parameters, else (default) - creates a new one

Returns

hypothesis object

References Mesh_Algorithm.Hypothesis().

def LengthFromEdges

(

self

)

Defines LengthFromEdges hypothesis to build triangles based on the length of the edges taken from the wire.

Returns

hypothesis object
