COMSOL 6.3 - Transformation

Transform (scale, move, and rotate) some 2D and 3D plot types.

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Transformation");

model.result(<pgtag>).feature(<ftag>).feature(<atag>).set(property,<value>);

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Transformation") creates a transformation attribute feature with the name <atag>, belonging to the feature <ftag>.

Transformation attributes can transform the coordinates of a plot feature by specified values for scaling, rotation, and moving. The transformation attribute can be added to arrow plots; contour plots; isosurface plots; particle plots; pellets plots; slice plots; streamline, streamline multislice, and streamline surface plots; surface plots; volume plots; and mesh plots.

The following properties are available:

Table 7-164: Valid Properties for Transformation plot attributes (if not noted, properties are for the Structured Transformation Type).
name	Value	Default	Description
applytodatasetedges	Boolean	true	Apply transformation to dataset edges (available for both transformation types).
ax2	double array	{0,0}	Theta and phi angles for the rotation, if type is set to linear and axistype is set to spherical for a Rotation3D dataset, and if enablerot is true.
ax3	double array	{0, 0, 0}	Axis coordinates (x, y, and z) for the rotation, if type is set to linear and axistype is set to cartesian for a Rotation3D dataset, and if enablerot is true.
axistype	x \| y \| z \| cartesian \| spherical	z	The axis type for a rotation, if type is set to linear for a Rotation3D dataset, if enablerot is true.
enablemove	Boolean	false	Enable moving (translating) the geometry.
enablerot	Boolean	false	Enable rotating the geometry.
enablescale	Boolean	false	Enable scaling of the geometry.
move	double array	{0, 0} (2D), {0, 0, 0} (3D)	The move (translation), if transtype is general, if enablemove is true.
rotangle	double	0	The angle increment for a rotation, if enablerot is true.
rotcenter	double array	{0, 0}	The rotation center for a Rotation2D dataset.
scale	Numerical array	Depends on the feature’s tag	The scaling in the x, y (2D and 3D), and z (3D only) directions, if enablescale is true.
translation	double array	{0, 0} (2D), {0, 0, 0} (3D)	The translation, if transtype is general.
transmatrix	double array	2-by-2 or 3-by-3 matrix of zeros	The base vectors of a transformation, specified using setIndex syntax, if transtype is general.
transtype	structured \| general	structured	The transformation type.
