Detailed Description

Tetrahedron 3D algorithm.

It can be created by calling smeshBuilder.Mesh.Tetrahedron() or smeshBuilder.Mesh.Tetrahedron( smeshBuilder.NETGEN, geom=0 )

This algorithm generates only 3D (volumes) elements for given geometrical shape and, in contrast to NETGEN_1D2D3D_Algorithm class, should be used in conjunction with other 1D and 2D meshing algorithms.

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_3D_Remote_Algorithm.

Member Function Documentation

MaxElementVolume()

def MaxElementVolume	(		self,
			vol,
			UseExisting = 0
	)

Defines MaxElementVolume hypothesis to specify the maximum volume value of each tetrahedron.

Parameters

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

Returns

hypothesis object
