Sector2D, Sector3D

Create a 2D or 3D sector symmetry dataset.

Syntax

model.result().dataset().create(<dtag>,"Sector2D");

model.result().dataset().create(<dtag>,"Sector3D");

model.result().dataset(<dtag>).set(property,<value>);

model.result().dataset(<dtag>).run();

Description

model.result().dataset().create(<dtag>,"Sector2D") creates a 2D sector symmetry dataset feature named <dtag>.

model.result().dataset().create(<dtag>,"Sector3D") creates a 3D sector symmetry feature named <dtag>.

This dataset takes data from another datasets and expands it using sector symmetry around an axis.

The following properties are available for Sector 2D and Sector 3D:

Table 7-130: Valid Properties for Sector Symmetry Datasets.
Name	Value	Default	Description
data	none \| dataset name	First compatible dataset	The dataset this feature refers to.
genpoints	double matrix	{{0, 0, 0}, {1,0,0}}	When method is twopoint: The coordinates of two points on the symmetry axis. Available for Sector3D.
hasspacevars	Boolean	false	If true, spacevars are made available for evaluation.
hasvar	Boolean	false	If true, an axis indicator variable is defined.
include	all \| manual	all	Use all sectors or specify manually which ones to include.
method	twopoint \| pointdir	twopoint	Decides if the line should be specified by two points or through one point and a direction. Available for Sector3D.
mode	integer	0	If sectors is odd or trans is rot: The azimuthal mode number use to transform the solution’s phase between sectors.
pddir	String array	{"0","1"}	When method is pointdir: The direction in which the symmetry axis points. Available for Sector3D.
pdpoint	String array	{"0","0"}	When method is pointdir: The coordinates of a point on the symmetry axis. Available for Sector3D.
point	double array of length 2	{0, 0}	The coordinates of the symmetry axis. Available for Sector2D.
reflaxis	String array of length 2 in 2D and length 3 in3D	{"1","0"} in 2D, {"1","0","0"} in 3D	If trans is rotrefl: The direction in which the reflection axis/plane (for 2D and 3D respectively) points.
sectors	integer >= 2	2	The number of sectors.
sectorsinclude	integer >= 2	sectors	The number of sectors to include (when include = manual).
sectorvar	String	Created from feature’s tag	Name of variable that evaluates to the sector number, which starts at 0 for the first sector.
spacevarst	String array of length 2 in 2D and length 3 in 3D	Created from feature’s tag	Names of variables that evaluate to the space coordinates in the coordinate system after sector symmetry expansion.
startsector	integer >= 0	0	Starting sector for manual selection of sectors to include (when include = manual).
trans	rot \| rotrefl	rot	If sectors is even: Controls whether the transformation performed between consecutive sectors is rotation or rotation and reflection.
